so after he put on the full-court press or whatever and you put up the NO hand.........did you then think that maybe you DID want something more? could this be more about YOUR feelings than his actions?
trust me, i get why you'd be gun shy about letting any man get close. and also how nice it must have been to have a "friend" that happened to be male and was of a different caliber (species???) from your ex.
so let's say the "line blurring" incident had NOT happened.
and then he tells you his possible plans to move away.
i suspect you'd probably still feel.........let down, disappointed, sad? that a person that you trusted and felt comfortable with might be going far away? a brick out of your wall of support?
