Thanks for the info truegritter. I've read some information about sibling incest but not nearly enough. I'm not sure how long this went on...I do know that she feels guilty about it because she said that she didn't really try to stop him. I've attempted to get her to try to talk to me about it, but she will not (I'm certainly not going to talk about it now, though during the summer, after her first bomb drop, I did mention that because of her experience she may have difficulties with intimacy, for example sometimes we would have fantastic sex and she would act completely cold to me for days after...in fact, we had great sex a week before her second bomb drop...its been almost total ice since then...and I can't believe that, that is just a conincidence).
Drug problems - mostly legal stuff...she takes pain killers like candy because of headaches. She recently tapered herself off zoloft and I know that withdrawal symptoms for that particular med can be ghastly (its funny how some of the legal stuff can be the worst for you).
I'll look for some of your posts. It's hard to get on here sometimes. Mostly at work...boss has started to notice.
Thanks folks.
