How do you handle a fight?
I find it hard to give my partner space after a fight.
Most of our fights are my fault bc I am selfish person at times.
I say the wrong thing when drinking and hurt his feelings.
I hate begin the bad guy and always apologize but I know he needs space.
What do people do to allow that? Do u act normal? Avoid them? Not sure what make it better or worse.
I love him with all my heart and hating myself for the ability to hurt him
Asking for space doesn't mean avoiding your partner, necessarily. You should act normal and polite around your spouse, but don't push them to talk about topics that caused the conflict you are experiencing.
There's an article that talks about this very subject. It discusses healthy conflict resolution skills, how to maintain calm when you're upset, not playing the blame game, and more.
