You are so not over-reacting but ugh, this is a little tough. I do somewhat agree that when you want truth but reward it with anger, this can be damaging to honesty in the future (thinking specifically of my children here).
BUT you are absolutely right that he is not keeping appropriate boundaries, if they are upsetting you.
Maybe the solution is going over very specific boundaries again, with other women? Then there is no room for him to wonder or feign confusion over why you are upset.
I would say if you can react calmly, it might help though? Something like, "I really appreciate you being honest with me. I know that can be difficult. I'm also sorry to hear that you were unable to maintain good boundaries. This is unfortunately something that isn't going to work for me."
Or something. And it's basically just me babbling, so hopefully it's not nonsensical...
