Until fairly recently I have always thought that if a dp leaves his family for an OW that the responsibility for that lies just with him.
He is the one with a commitment that he has decided to break to be with the OW. She might be free of any prior commitment and in a position to start a relationship.
But if starting that new relationship means breaking apart a young family, and the OW knows that, should she also carry some of the responsibility? I am beginning to think that she should. Aibu?
