<human>: Provide a brief overview of the text.

Ex-GF and I broke up in January 2014 after a three year relationship.  Needless to say after three years we made and maintained a lot of the same friends.  Some of these friends were friends of mine long before we dated.  Friend groups from my freshman year of college that she has forced herself into.  I should say that I am friends with NONE of her friends.  Not that she really has any of her own now, she basically just stole mine.  It's so bad that if any of these friends invite me to do almost anything, I know she will be there. 

So I'm looking for advice.  What should I do?  I have no desire to see her.  I'm over her as much as someone who still sees their ex rather frequently can be.  I've dated other girls and might start seriously dating someone soon (fingers crossed for this girl).  Having my ex-gf in my life is something I'm not interested in. But a large chunk of my friends still associate with her.  Hell, she banged every dude in one of my friends bands after our breakup excluding him thankfully because he's married.  I don't want to know these things, or see her, or talk to her, or anything.  But if I keep these friends I'm forced to see her.
<bot>: 1.5 years after a breakup I'm still forced to see my ex because of all of our mutual friends.  I don't want to see her but I don't want to cut out all my friends.
