am i wrong?

so my partner is not a very level headed person when they are angry/irritated/etc. no he is not abusive, he is just the type to maybe punch a wall or something to release some stress. I feel like everyone is entitled to their way of expressing themselves but not at the cost of damaging walls or doors or anything. I tell him to punch a box or just something that isn’t going to cost money to fix. he says he feels “trapped” and like when it comes to me he feels like i’m trying to control him.

All i try to do is remind him that he has to pay for these damages and the hour of being upset is not worth damaging your hands or property.

At this point, I just want to let him do whatever and suffer the consequences. I am not his mother and I am not trying to be, I try to be a helping hand and it always backfires. Am i wrong for trying to just help lol?
