Hi WL. Im sorry about the stress. I would recommend that you do some research on Bipolar Disorder, Manic Depression is what they used to call Bipolar. Also, there are some threads on here with a WAS who was bipolar. And honestly, the more you know about it, the more you can keep an eye out for it in your kids, though I firmly beleive that family support and strong social connections can overcome a lot of genetic predispositions.
Its a tough one, but just like anything else, your W isnt going to change until she doesnt want to be sick anymore, I guess she hasnt quite hit rock bottom yet. You know, Im really glad that you are in the place the you are now, things might be very different right now if you hadnt been able to detach like you have. And her going back to her druggie friends is no surprise, shes could be trying to self medicate. I have also noticed that the people who I know that struggle with their bipolar disorder can sometimes be very selfish people.
I joined match.com, I looked at some of the other ones, and they seemed like they were just an online equivalent of the bar. eHarmony wouldnt do anything for me because Im not D yet... imagine, some people still have morals!
I guess I gave the wrong finger to the wrong man...
