Was my boyfriend wrong for backhanding his teen son.. the son hit him back too?

After yesterday's scene, I'm not sure of whether to proceed with this relationship or not. I'm 27 and he's 39 with a 16 year-old son who will turn 17 in December.

During a heated argument the son called him a dumbass and he backhanded him hard, yelling "Don't ever talk to your father like that". His son punched him and yelled "Don't f****** touch me, do that again I'll hit you back again".

My boyfriend isn't talking to him because he thinks it was still wrong for a son to hit back his own father. He went on explaining that he never hit back his parents. I've voiced my opinion that both were in that wrong and my disappointment towards him that he thinks a teen backtalking merits getting hit. He scooped to his son's level, actually worse because he's an adult. So basically if someone is frustrated because bad words were said, it's right to take out your anger and hit first but then get shocked when they hit back?

I'm thinking of reconsidering my relationship. I wouldn't want to have my own kids with someone that thinks it's ok to hit for words and whenever you're frustrated but have a double standard that a teenager (esp older one) can't hit back.

An older teen backtalking means that perhaps their voice isn't heard and they're expressing something lacking. Yet too many parents like him really think a teen backtalking deserves to get hit... that hitting is the answer when they frustrate you and say words you don't like. My boyfriend backhanded in anger.
