Sounds like he can't even be decent about anything. I'm sorry to hear it and about the horrid day you had!! He's probably belittling you because of how bad he feels over what he did. It's pretty classic from what my own counselor said after my divorce. My ex would use any and every excuse to make me sound like an idiot and to criticize me so that he could feel better about himself. I finally completely cut him off.
I realize you can't because of your child, but perhaps only communicate by e-mail and only about childcare arrangements?
I hope that now that you have a place of your own, you can truly begin to heal! I'm happy that you now have your own safe and serene haven just for you!!
