Is AUTHOR wrong in the post ? POST : Hey, AITA. I recently got called an asshole and I'm wondering if it's true.

My boyfriend and I (together a year) like to play games online together, a lot of times MMOs. One of his friends, we'll call them Alex, tags along with us. Usually invited, sometimes not, but my boyfriend doesn't care if they tag along across games.

Now, I don't like Alex a bunch - I think they're a little dense and slightly annoying, but I treat them with respect and I'm as nice to them as I would be with a stranger. However, apparently they complained to my boyfriend that I only talk to them or play with them when he's there and that I am bitchy and he should tell me to be nice to his friends.

I haven't been mean to Alex that I know of! I play with them, help them in game, tell them gear they need when I'm asked, protect them from monsters they don't know how to fight... maybe I'm a little condescending in my head, but I've never been a jerk to Alex because I care about my boyfriend and this is his best friend's spouse. 

When my boyfriend logs off, I tell Alex goodnight shortly after so I can go spend real life time with him. Alex's spouse (my boyfriend's bestie) also sent me a text asking why their partner isn't good enough for me.

I feel like I'm taking crazy pills, am I really being an asshole here? I'm a private person and keep most people at arms length. I can count my friends on one hand, the rest are aquaintencis that I'm cordial to when we see each other - I'm friendly and joke with them like normal, I just don't get personal and close with them.

For the record, my boyfriend told them not to call me bitchy, because he's always there when we play and I'm pretty nice to Alex, and that I'm like that with basically everyone. Polite but distant. 

I'm a bit anxious and annoyed now though, my boyfriend has been best friends with these people for over a decade and I don't want to cause a rift between them. I'm happy he's sticking up for me, but am I the asshole here? 

tl;dr play game boyfriend friend, boyfriend friend mad
