You are both indifferent to progress, which is what a forward-moving relationship requires. Progress is mutual respect and using your heads to solve problems. That is not love. That is not understanding, compassion... zilch in the empathy department.
Hitting or aiming to shock another for attention lowers your level so much.
God gave us language for a reason... who do you think you are, to think with your fists? Or hand? Or any other object whatsoever????
So now you come on here for sympathy. Uh. RIIIIIIGHT.
Bologne.
Get away from each other and get anger management classes. He is not your partner. He is trying to figure out how to keep his son in his life, and you just hit him, probably many times before.

Either way... Problem: You are still both there.

There is no sympathy here.
Dont come on here looking for people to see your reasoning for hitting him.
He didn't!
Go.
Get help.
There can't be a next time.
Once you hit another, game over.
