Question..

Just a general question.. My boyfriend got drunk and we ended up arguing.. At the end of the night he ended up punching the screen in my car completely smashing it to pieces. He obviously doesn't remember.. He blacked out. I'm having a hard time moving on from this,possibly due to my past relationships which were very toxic, aggressive, and unsafe. He has never broken any of my property before but I do see he has anger issues.. (I.e. He hits things when he gets mad, raises his voice at minor things, etc..) am I being childish for not being able to let this go? (this happened months ago)
