I have anger management after my bf cheated.

He cheated on me a year ago in March and we broke up for 3 months then got back together after him begging me and I gave him another chance. He changed for the better and I learned to trust him again. But I felt like everyday my anger grows bigger and I would get mad about everything, to anyone. I feel like crying most of the time because I would get so mad about everything. Then suddenly I start thinking about the time he cheated on me and I would get angry even more. I love him a lot and he really did change and apologize and owned up to his mistake and took full responsibility and knew he was wrong. I don’t want to end it because it’s going great and we have grown so much together since last year. We’ve been together for 2 years.

Idk wtf To do because I get so mad over everything including some of the things he done and then I would trigger everything down to when he cheated. It’s been almost a year and I’m still angry. Sometimes I don’t even think about the time he did it. To make it worse it was with my best friend and that’s what also makes my anger issues worse, the fact my “best friend” lied to me and never apologized to me about it. So that also makes me mad af too when I think about both. Help me.
