I met this girl 2years ago in my freshmen year of college and we became really close friends. At the time she was engaged and had a child with this one dude. I met him and became friends with him also. They moved away for a year but we stayed in touch over the phone. Anyway they have now moved back to Peru and are going back to college. She is in my social psychology class and naturally being friends we sit by each other all the time. She is now married to this guy. Now the problem is that she has expressed sexual interest in me, and things with her and her husband are not going very well at all. I had lunch with the two of them yesterday and they didn't say a word to each other. She just talked to me while he read a book and was silent. After lunch I walked outside with him and I asked him why he was so obviously pissed. He just answered by saying "how can I not be pissed?" I asked him if he wanted to talk about it or if I could help him out with something. He told me not to act like I know what hes dealing with, very defensively. I told him I didn't know what he was dealing with but even if he just wanted me to listen and not say anything I was there. He declined. About this time she joined up with us outside and we had to depart for classes. The again didn't speak to each other. What can I do to help them?
