I too have mommy issues of my own (and daddy issues, but those are bit different.) My mom did love me, I don't doubt that and I loved her, but she did screw up in some things in the way, that I still don't think were okay. I have forgiven her, but that is another matter. I have to say I needed to take some distance to her when I was around my twenties and during that time our relationship was strained. It did get better before her way too early death though, but first I did need to heal a bit and then I was able to really forgive her.
What I was very angry to her were mainly that she failed to keep me safe physically and mentally, and that she really didn't make enough effort in those areas in my opinion and she even caused some of it by her selfish choices. My mom came from somewhat wealthy family and had strained relationship with her parents. Looking back, tried in every possible way to annoy them. She was also very opinionated and principled. Hippy and communist. She despised her parents values, lifestyle, heritage and so on and was adamant to do everything differently with me. While she felt she had too strict upbringing, she tried to do Summerhill upbringing with me, where she felt her parents had been too status orientated, she wanted to bring me up anti-materialist, where she felt her parents were sticking too much with 'their kind', she wanted to make me scoff to our heritage, where she felt her parents had had too strict expectations for her, she often told me,that I could do anything I wanted with my life.
Of course it didn't work like that. Okay, Summerhill-thing she was able to do at times, but even with that, she actually didn't that much respect my free will, but tried to manipulate me to freely want what she wanted. Her ways of trying to make me believe that material things don't matter, made me security seeker (after spending years really scared about if we would have something to eat or place to sleep do that to a person, even though we actually seldom did go without, and looking back my mother was well aware that we really wouldn't, or only if she really, really wanted to.) But in fact that constant fear and worry left me with much worse marks than those few nights I did go to bed hungry or we really were without place to sleep.) In stead of scoffing to our heritage I very much embraced it and that and need for security were partly the reasons I married someone like my husband (whose my mom didn't like at all, by the way.) And while she was very vocal about not having expectations for me, she unverbally made very clear what the expectations were, and they were high. And she also made it clear, what a displeasure it was, that I failed to fulfil most of those expectations.
By the way, I of course decided not to do same mistakes my mom did: Now I have one kid who scoffs to the white picket fences I have made so much effort to maintain and who I failed miserably to protect and other, who tends to complain how I have way too high expectations for him.
The things I had hard time forgiving my mom was how she forced me to be a grown-up in our family from early on, to worry and take care about financial matters, food, schedules and structure, all kinds of grown-up things way too early. And not just for myself, but also for her. And she let me be scared about our surviving, when she actually always had options in her back pocket, even if we didn't have any money left and no food in cupboards and rent had been due five days ago already and I was going frantic, she actually had options. She had skills she was able to turn into money in short order and also as long as it was me, who was about to go hungry and homeless, her parents were willing to give her money, if she just asked. But I didn't really know that, so while for her it was play, pretence of being this poor, proletarian person who was suffering for her ideology, for me it was real. I'm not sure if she ever really understood that. In her ideology children are just small adults who should be treated like adults, maybe she really thought I was capable to adult reasoning and seeing, that we really never had any danger to go lacking.
My mom also never settled down, we were always moving around, for example one school year I did go to four different schools. She also had about half a dozen husbands and countless boyfriends and we lived with many of them too. I totally lost count how many 'step-fathers' I have had. Some were nice, some I liked a lot, some were not nice. Few were physically violent towards my mother, few were substance abuser, few yelled and said horrendous things to my mom or me, few were criminals and couple were physically violent towards me too. One badly so. That one, and not leaving him even after he beat me good couple times, I was very angry to my mom for a long time. I was never really sexually abused by any of her men, but one did harass me. He probably didn't consider it so, it was mostly just implying and verbal harassment masked as jokes, slapping my butt or touching my breasts also as a 'joke', but it certainly made my young teenage self really uncomfortable. But that my mom never really saw, so it was easier to forgive her.
But maybe the thing I had hardest time to forgive her, was her keeping me from her parents in whim. She did let me visit, even let me to their care for months, and once almost a year, when it suited to her, but when she got angry with them, I wasn't allowed to meet them or have contact with them. And while I do believe they may had been very strict and even harsh with her, and while I do believe she had some legitimate beef with them, they were different for me. They were older, had thought things through and of course your own kids and grand kids just are different thing. So they were very doting grandparents and I adored them and safety and structure they were able to provide me. And her taking it away from me as a whim, was very hard for me.
I apologise for long-winded sob story, but my point is; few have perfect parents and gripes tend to go through whole family tree, small changes, but often issues stay similar. There are some quite functional families and some more dysfunctional and some downright tragic (with me, that down right tragic family tree is on my dad's side, my mom's side is just having an erratic functioning profile
) but in the end we just have to play with the cards we are dealt with. Some get better ones, some downright horrible (if you happen to born as a quadriplegic child of a Bangladeshi street prostitute, you really don't have much chance, most get at least a bit luckier), but it is, what it is and in the end we just have to do our best to make the best of what we have been given. You do, your daughter does. Understanding and accepting that and learning to forgive is a key to being more content, but even that can't be forced, but a person actually has to get it themselves.
When we are in our young adulthood, we are supposed to go through things that happened in our adolescence. Look at it all with adult perspective. As children, we are powerless and our survival depends from adults around us taking care of us, and kids instinctively know that and will do absolutely everything to please the powers that either keep them alive or don't (even though it doesn't always feel like that if we have been able to provide our kids enough safety that they dare to oppose us. But kids who are lacking even basic safety do not dare to do that.) When young adult, person is not as depending of the parents any more and it makes them able to critically look back. And if there has been more than little dysfunction, it is normal to become angry. Taking some distance, going things through and trying to figure out why things happened is often needed for us to get over and heal from dysfunctional elements in our childhood. To learn and grow. And often true forgiveness can come only after that.
