Amazing, you cannot say anything for sure until you hear both sides of the story. In my experience, people always talk about the marital problems with more than just a little exaggeration. Having said that, I think your friend "Anita" should talk to her husband about her feelings about him. She should tell her that she was married to him against her wishes and his tastes are not compatible with hers. If Ramesh does not listen, both should talk to a common friend - someone mature enough.

My own wife has destroyed my reputation by talking to everyone about me as if I was a monster and I mistreated her. I admit that I did act in a way that was unfair to her for some years but she kept her feelings to herself. If I had known that my actions were having a very negative effects on her I would have stopped it then. But she told me when it was too late (for her, as she says). Its been a long time since I stopped my habits that she did not like but she did not forgive me and instead started treating me very badly. I took her abuses in hope that her anger towards me would subside and we may get together some day. But she kept growing worse from bad. And finally I packed up and left. I still want to help her from afar but now I cannot live with her. A few of our friends who are close to us have not begun to realize that what she told about me were not true but false accusations. If she had told me about her feelings right at the beginning, things could have been better. However, she kept it inside her. And she told me (in fact, she told other people first and they told me) too late. She had made her mind up.  

Your friend Anita should also talk to her husband. She should ask him is he wants to save the marriage and cooperate with her. They should try to understand each others' problems and their wishes. But it seems it has been too late for Anita too. She did not talk about her problems with anyone for a long time and kept it suppressed inside of her. However, there is still a chance that they could work it out. Ask your friend to give it a try.
