TITLE: I [20F] hate my SO's [25M] friends.
POST: My SO and I have been together for over two years. I'm 8 months pregnant and we couldn't be happier. My family loves him, his family loves me. We're totally in love and happy. I'm the only girl that he's ever loved. 

But, we live in a neighborhood that he's lived in his whole life and occasionally I'll have to see his old friends.

I really don't like some of his friends. I probably only really like 2/6 of them.. My SO doesn't really care for them either but he feels like he has to talk to them and play nice since they've known each other since they were in diapers. 

Some of his friends are just plain rude and will act like I'm not even there. I have extreme social anxiety and don't know how to react to this. My SO doesn't seem to notice... But it all could be in my head since I don't really try to talk to them either.. 

How would you deal with this?
TL;DR: 
I hate most of my SO's friends. Some act like I'm not even in the room with them. I have extreme social anxiety.. How do I deal with this and make it better?
