<human>: Summarize the given text in a few sentences.

Just a quick thing, I've been in a long-distance relationship with this guy for almost four months. So please, don't be harsh on me because of that fact... I know LDRs aren't really smiled upon nowadays... 

My boyfriend and I use games such as Battlefield 3 and Black Ops to spend time with each other, and while I used to enjoy playing with him, I've now noticed that every time we play, I get extremely uncomfortable when he suddenly starts shouting and cussing at the game and the opposing team (and sometimes insulting me without realizing it). 

I've tried discussing this with him several times. The first few times he said he would "try" to not rage, but he would go back to his ways (though he would always apologize when he noticed my quietness / awkwardness). I finally told him it makes me uncomfortable and stressed, but lately, his response is (and I quote this from what he just told me) "I get angry when I'm not doing well. Its just who I am. I'm not the only guy in the world who rages. Give me a break."

Tonight, I finally just told him that I didn't want to play with him tomorrow because it was just way too stressing for me. He got offended (of course), but I made sure to tell him it was his raging, not him personally, that I didn't want to deal with.

He's generally a sweet guy. Sometimes he's self-centered, but most of the time, he's aiming to make me smile / laugh, trying to do activities with me... but lately, this is just a huge bump in the road (and a turn-off).

What should I do? Do I just drop one of the few activities we do together? Or should I just grin and bear it when he begins to get angry? I'm seriously clueless as to what to do...
<bot>: My boyfriend (in a LDR) tends to rage hard at video games and isn't wanting to change that, despite me telling him it makes me very uncomfortable. What should I do?
