Alejandra, welcome. If you would like to start your own post, you'll likely receive more responses.
I had the same considerations about how to detach with love. For me, I had to shift my own faulty thinking.....for instance, I thought that (mother) love meant that no matter what, you step in and help, you are always there, you do whatever it takes to help your children, mothers are supposed to give to their children no matter what, in other words, it was all based on my daughter being the focus and the priority..... my needs were secondary ....I had myself locked in a box with all my beliefs intact, and I couldn't get out. I think the one place that helped me to correct that thinking was in a support group with other parents with difficult adult kids. I listened and saw myself. And, I could see the way out for them, but not myself. The therapist kept interrupting my beliefs with a different perspective. I had no idea I had choices. I had the choice to detach, to walk away, to refrain from action, to not give all my time, money, support and help to someone who not only did not honor my support but wanted more and more and more all the time. I learned to put myself as the priority. I learned to figure out what I needed and wanted FIRST. My beliefs about mothering and love changed....it now included me and my needs.
I also learned it is best for me to NOT know everything. For me, needing to know everything was me trying to control everything. It took awhile, but I stopped asking questions. If she wanted me to be involved in her choices, I would say, "I know you will figure it out" and leave it at that. It is hard to be on the sidelines of their lives when their lives are nothing but drama, intensity, making poor choices and often being nasty to us. At this point, I have slowly disconnected from my daughter. As each drama erupted, each time I was pulled in, I stepped back just a little more. Now we text occasionally and she knows I love her and want her to succeed, but that for my own well being, I cannot take this journey with her. I've told her that I cannot know the details of her life, it is way too worrisome. It took time for her to stop involving me, but she did. I see her occasionally, on holidays, birthdays, special occasions, but day to day, i don't. We don't chat on the phone or text often because it is not a typical conversation, it is almost always her telling me her latest bummer......I don't want to hear it.....it took me time to figure out what it is that I wanted and what it is that I was willing to do or listen to and what I wasn't.
When she was evicted I told her that like Luke Skywalker, ( she's a huge Star Wars fan) she was now beginning her Heroes journey and it is a journey she must take on her own, without me, in order to find herself and find her life's path. She understood that. I told her my enabling thwarted that journey for her and now that I wasn't enabling, she was free, we were both free, to find our own lives.
With all of the professional support I had to learn to love myself and put myself first I got to a point where I could communicate to my daughter in a way she understood...she could see how much her lifestyle choices caused me worry and pain, so my choice to distance myself from the pain of it while still being on the periphery of her life, was something I did for ME.
No it doesn't feel like love in the beginning when you've been used to giving, giving, giving and then you stop, it feels weird for awhile. I came to believe that the most loving thing I could do was to hold my daughter responsible for her choices and to refrain from responding to those odd requests they tend to involve us in. I think you said all the right things, I would have responded similarly, but it doesn't feel good......especially when we are used to saving them which temporarily diminishes OUR fears. When we don't save them we don't get that release....there is no 'feel good moment' about it like there is when we rescue them....so it takes time to adjust, for you and for your daughter. I also had to get better at living in uncertainty and letting go.
Hang in there, this is hard stuff. Keep posting, it helps a lot to write it down and get support. Stay the course, you're taking all of the appropriate steps, just recognize that it really doesn't feel good....this is a very different way of parenting and we have to learn the lay of the land.
