Now I'm thinking about the behavior you've described with him from the beginning when he started waffling, and I suspect this man knows he has issues, like anger....perhaps why he has been reluctant to commit to a REAL relationship. As September so wisely said, this is NOT your problem; it's his, and you would be wise to walk, NO, RUN away from this man.
Do not enable him in his unbalanced behavior by making excuses for his fear or anger issues. It's way too early in a relationship for you to be having this kind of grief!
