I want to beat my ex
Are you serious? Why do you want to beat up your ex?
He was a jerk and I'm always pissed off about him.
Exes can be difficult to deal with especially if they are still in your life but it is not good to use violence on him. It will just get you in trouble with the law.
So I should take out my anger on a wall?
I just think it's wrong to hurt anyone and you should just move on from your ex entirely. Leave it in the past.
