That really sucks. I'm sorry you're going through that. I don't really have any advice - it sounds like you are making the right choice in ending the relationship, though.

Something similar happened to a friend of mine a few years ago and it really was mystifying - she was very convincing about how she planned to leave her boyfriend. I don't get how a person can keep up that kind of lifestyle for so long - or why they would want to string two people along like that.
