Aug. 21 will be my 10 yr anniversary, but it will also be 2 yrs from the day I found out about my husband.
I'm still dealing with thing, most my anger at the situation and the trust. You being there to listen whenever she needs it, and helping when she needs it. Is the best help you can give her! I had some WONDERFUL friends that would just listen to me rant and rave, they never pushed always there to support me. When I could start talking about it without crying they'd ask questions. I went to a counsler, and that helped a lot, cause even though I had my friends, talking to them got to a point where it didn't help.
My counsler was wonderful and helped a lot. I asked him to go, but he wouldn't. But by me going, I'd come home and he'd follow me around until he got the courage to ask how my session went. By me telling him what I was told it helped him.
She needs to confront him, that she's found out about him cheating on her. That he needs to make a decsion wheather he wants to be a family with you, or if he wants to be with her. That his decision is to be made right then!(This is VERY hard to do) If he intends to stay, and work out the problems then no more going out with friends, no more "traveling" if he can help it (i'd ask for proof from his work) They should also try to seek out someone to talk too, and work to the root of the problem, cause there is always something deeper that helped contribute to the affair in the marrage. It's usually something petty on the man point of view.
I hope that your friend stays strong! Tell her she needs to be strong for her daughter and make decisions based on their daughter and not selfish, vengeful things. There will be lots of fighting, crying. I still hurt from it and it's been almost 2 yrs. It's a constant work in progress, but my husband has changed (used to be the party guy, always going out. He never grew up after we had kids. I was the only one who did that. Through out it all, he's always been a great dad.)
