How do you not get mad when your boyfriend is mad at you for something stupid?

Maybe you should figure out what's really bothering you. You already know it isn't the "stupid things", so what is it?

My best advice is to write a list of rules/things to remember/ect. I have a list that is my rules to success ( in being happy, I suffer from a mood disorder) I wrote a list of 10 things that help me focus on being a good girlfriend and stop the nagging. For example I wrote remember I am his girlfriend for a reason, no one else is and trust completely always, and so on. As dumb as it sounds I read it daily and it refocuses me. I tend to over analyze things, dwell and draw dumb conclusions. So if you write a list or even a short note to yourself, include why your relationship is good and it might help you to believe and live it.
