<human>: Could you distill the essence of the text into 1-3 sentences?

My boyfriend and I have been together for just over a year. We love each other very much. He is sweet and thoughtful. He has anger issues, though. I think he gets it from his dad (his mom and dad divorced when he was very young, he never sees his dad but his mom told him that his dad is the same way). When something minor doesn't go his way, he rages. This happens often when we're gaming together - if we lose, or if he dies, he screams and rages. He told me that he has broken his Macbook in the past because he got really mad and punched its screen. Whenever he rages like this, I get scared and sad, and I feel that it's my fault. I could never deal with people yelling (I immediately cry if people yell at me... it's just a reflex). I asked him if he does this around his friends and he said that he doesn't. He told me that he shows his anger around me because he feels comfortable around me and can open up more.

How do I help him deal with his anger issues? I like that he can be more open around me but it truly upsets me when he gets mad. Is there anything I can say when he's mad, to make him feel better?

My poor writing skills can't express how distressed I am about this. I can't go on a date without fear of something getting him angry and ruining our date. I think my parents will disapprove of him if they find out about how easily angered he is. Please help!
