Advice please

Do you or your partner hold a grudge for a long time when you have arguments?

My bf and I are completely different when we have arguments. I usually get over things pretty fast. I like to talk it out or sometimes just sleep it off. And the next day, I am ready to move on and act normal again. Unless I got cheated on or something, but I’m talking about small disagreements and arguments.

My bf gets so mad, he avoids me, gives me the silent treatment, won’t text me back, goes in the other room, doesn’t want to talk or cuddle or anything for about a week if we have an argument.

Just 2 days ago, we were absolutely fine, he was so loving to me and sweet to me as usual. We had an argument and he’s been acting like a completely different person.

What do you guys think about this?
