Throwaway account because boyfriend is also redditor.

I am f/22 and boyfriend is same age. We have been together for 2 years now. I am in a co-ed fraternity and I'm worried my boyfriend is uneasy about some of the stuff we do. My fraternity is probably 2/3 male and 1/3 female, and we are all engineers. For example, we like to throw kickbacks at each other places so I enjoy doing some brotherly bonding that includes drinking. I think my SO may be jealous even though he tells me that he is not the jealous type. I was in the fraternity before we met so I figured he would understand that we do have parties. We go to school in different cities so we don't see each other as much as we like, maybe 2 weekends in a month if we are lucky. He was also angry at me for not telling him that I went clubbing with them during our annual retreat until I got back from it which was the day after. I went with 10 girls including me and only 3 guys. My previous boyfriend broke up with me, partially because I was in the fraternity which is why I tried to make it clear to him that I was in one when we started out.

In the beginning when he was able to hang out for longer periods, I invited him to some of our parties and dinner thing and he enjoyed hanging out with everyone. Now that he's been concentrating on school, he's not around to partake in a lot of the events.

So reddit, how do I make my boyfriend more comfortable about it? I've told him that they are just my brothers and I have no intentions of dating any other guys. Also, how can I get him to feel less angry when I want to go out and do stuff with them? This is my last year at college so I want to make the most of it in case I move far away for work.
