I have learned the hard way through naivetey that when other people complain to you about their relationships, it's best not to get involved, offer personal opinion or give advice, because if taken, you most likely will be blamed if they decide later that was not the choice they wanted to make. If you don't offer your opinion, then you can't be blamed and all decisions will be on the other. Not that one deserves to be blamed anyways since no one put a gun to their head but that is people for you. No good deed or at least intention goes unpunished it seems. Big mistake to get involved. The thing is even though people may complain looking for sympathy, often they really don't want to leave or they may actually care for the person and if you get involved, you could eventually be seen as the evil villain in the middle trying to break up a relationship even though you don't really care either way.
