My boyfriend and I occasionally fight (don’t all couples?), and I always let it get out of hand. I hold grudges, dredge up the past, and say mean things. Does anyone have any tips on how I can calm myself down in the middle of an argument so I don’t end up saying or doing something that I regret later? He has a habit of doing things that he knows will make me mad in the middle of a fight and it’s so hard to just shrug it off.
