That's just awful. I'm sorry to hear that you've been let down, but at least you're making it clear to him that he won't receive any more support until he starts giving you respect and putting in his share of the work to maintain the relationship. You are doing so much by staying at his side at this time. Keep evaluating whether it's worth it though... being hurt/disappointed/disrespected is all part of the game and it may never end. I don't know much about you, but he is only your boyfriend, you may not have kids, and there are a lot of other fish in the sea. Good luck!
