My best friend [F18] and I [F17] have been friends for two years now and we have had some bumps in the road, but we've always resolved them and we're very close. Last year I dated my ex [M17] for three months, who had been my friend long before I even met my best friend. We had a very messy break up which was never fully resolved. He broke up with me for reasons I still do not know and I was very hurt and said some really mean things that I completely regret. I apologized to him back in July, but he never responded and we have not spoken since. 
During our relationship (me and my ex's), my best friend and him became good friends because neither have a lot of friends and they live in the same town (I live about an hour away). This caused a rift in my friendship with her because I was hurt and she was insensitive about the whole situation, she still hung out with him even though I wasn't over it (we stopped speaking for 2 months because of it, but we reconciled and are now close again). I have been completely over my ex for awhile now and the situation is very awkward. He is good friends with her, and I am good friends with her, but we ignore each other's existence. 
It's been over 6 months since the whole situation and a year since we dated. I don't know how to fix it? And should I? I feel like I gave him the opportunity to fix things with me and he chose not to, but that was months ago and we're both different people now. I just think it's ridiculous that we ignore each other when all three of us (me, my best friend, and my ex) could be friends. I'm not saying I have to be best friends with my ex or anything like that, but I'd like to be on speaking terms without it being awkward. What should I do?

My ex and I are good friends and we ignore each other because we are good friends. I don't know how to get past this.
