Trust your instincts. I am kinda in the same boat. If he can't respect your feelings and try to understand how his behaviour is hurting you, and there is no compromise, then respect yourself and walk away. I have so much doubt with my guy it has turned into him resenting me for my lack of trust, hurt, etc. that he has blamed me for his low libido because of my depression, questions, etc. Hang in there and realize that your intuition is usually right.
