Tragic dilemma

Several years ago I met a married woman online. Although we lived several miles apart we met up and slept together. I fell for her but as she was married our relationship continued online only. We stayed close and my feelings developed for over time. A few months ago she added an ex school boyfriend as a friend on a social networking site and unknown to myself and her husband they started an affair. Her husband found out about their affair and took his own life. She then told me about her husband and this other guy. At the moment she is still seeing this ex boyfriend but has confided to me that she dosnt trust him and he tells lots of unessacary lies. I still have strong feelings for her but Im torn as to which way to go? Do I stay friends with her and be there for her if or when this new relationship fails or just cut all ties with her altogether?

If you like sharing your partner, then by all means...keep her. Otherwise, this woman seems to fall into the saying "once a cheater, always a cheater". Cut her loose and everything that reminds you of her...time heals all wounds!
