<human>: Sorry this might be kind of long.. but any input would be grateful here

So, my boyfriend and I have been dating for now almost a year. In the beginning he took me to meet his friends, and we all got along great. We all had the same interests. I'm into video games just as much as they all are. It was awesome because we all played the same games, and when we would hang out everyone had the same movie tastes and everyone could peacefully agree on something to do or watch. 
(I'm not one of those girlfriends that constantly needs the attention on her, and I'm definitely not one that needs to make the decisions for everyone.) Basically, I went along with everything my boyfriend and his friends wanted to do, and I honestly didn't mind because I enjoyed the things we did.

Fast forward to the past couple of months, and now his friends won't play any games with us because we are "bad at them". I'm no professional at games, but I'm not completely terrible either. We are all average casual gamers. Needless to say, I was hurt that they didn't want my boyfriend or me playing with them anymore. Also, the last times that we all hung out they would say somewhat rude comments to me, and I would brush them off, try and laugh, and then try to forget about it. 

Now, I have been nothing but nice to his friends. Some of the things that I've done for them are having them over for LAN parties, just having them over to hang out, letting them eat my food, borrowing them money when we went out for food, bought one of them a birthday cake, gave one of them a haircut, when one of them bought computer parts, I put together his whole computer for him, and when they would need girl advice they came to me, and I always tried to help them out to the best of my ability.

I'm just wondering what I did wrong that they aren't barely speaking to my boyfriend anymore. They haven't tried to talk to me either for about a month and a half. I'm at a loss here.

Can you give me a shortened version of the text?
<bot>: boyfriend's friends won't talk to him or me anymore, and I have been nothing but friendly to them throughout our whole relationship.
