Hi. I think, as time goes by and you still feel you want to post, you should start a new thread so that more people can see it
Until I checked I thought somebody had just popped up an old, old thread and did not realize you have been posting updates
Welcome back.
I don't begrudge you your feelings at all since she isn't your daughter. In fact I think it is common when you marry somebody who has a child who is a major problem and breaks your loved ones heart. However, your wife is going to be unable to just walk away and detach this early in the game. Is this her only child? If so, even harder. Been there, by the way.
I honestly think that this child's boyfriend has introduced her to drugs. There are signs of drug use that she has and you don't have to catch her doing any drugs for her to be using them. My daughter sure fooled us. In fact, until she quit and told us the whole gory details, we had never guessed how deeply involved in drugs she was. So I wouldn't chalk losing weight and deteriorating hygiene just down to junk food and laxness. Junk food usually amps up your weight. If she is throwing away everything she once cared about, including you and your wife, that is a STRONG red flag for drug use that goes beyond marijuana. Kids tend to get very rebellious, ornery, and puzzling while using drugs. In a sense, they don't want to be around you because you and your wife are good and decent and she knows darn well she is screwing up her life and it shames her more to be around you (a little possibly flawed and layman's psychology here, but my own daughter did mention this to me..."If you'd known what I was really into, you would have been so sad and ashamed so I cut you out.") Now I'm not saying she is on drugs for sure. But it is awfully suspicious that she is acting this way if she isn't taking any drugs. And what does she see in this boyfreind? A drug supplier? Forgive me for being skeptical. My own experience makes me very cynical. Sounds like bio. dad is now wearing on her nerves and that she will bolt as soon as she is eighteen and then you will find out what is really going on. Of course, I actually help she comes to her senses and that scenario never happens...again, I am cynical t hat difficult children learn and do better unless they have fallen to their rock bottom and have the strength AND desire to do the hard work required to pull themselves out. Many don't. Some do. Depends in my opinion a lot of intelligence and ability to have the insight to face the fact that life is bad and only THEY (the difficult child) can make life good again.
Sorry I went on a rant. I feel so badly for both of you. Do seek out counseling, whether you are more comfortable with a professional or pastoral counseling or anyone else who can help you support your wife during this difficult time.
I agree with IC on the curse of DNA. It is a part of who your difficult child is, the good and the bad. Sometimes you can have the best intentions and be the best parent on earth and DNA dictates that the child will experience your good intentions in a differently wired and misconstrued way that is in no way your faults. I believe nature trumps nurture 80% of the time.
Thanks for the update. Remember...maybe next time start a new thread so that you can get more feedback. We certainly are happy to give you our .02
