Mojo, I haven't read every single post in this thread this afternoon, this is my opinion: if you don't want to sleep with this guy any more, don't. You don't need any rationale from the past or present. There don't need to be any rules or principles. It doesn't need analysis. Not wanting to, for ANY reason, is a good enough reason. If you change your mind, that's okay, too.
Who officially broke up the relationship? And what was the official reason?
