<human>: Can you provide a brief overview of the text?

Last night I went out to the local bar with a friend to have a few drinks, dance and have some fun. My ex and I broke up back in February, it wasn't exactly the easiest, nor pleasant thing that we had to do. 

He hasn't spoke to me much since. I don't really care about that much anymore, but it does hurt me quite a bit. We've chatted over text a few weeks ago and when we ran into each other last night we hugged and had a quick "hi, how are you" type chat. It was nice.

Anyway, later in the night I was sitting near him talking with my friends when I overheard a girl he was talking to say something that pertained to our break up. I heard her say "I would never do (blank) to you." Then he started talking really quietly to her. I was kind of shocked that they were blatantly talking about that right there. 

I just asked my friend if she was ready to go and we left. I ended up crying on the car ride home. 

When we were together I had some issues I was dealing with and it came out towards him and I hurt him. He knows and understands that and that's why we aren't together anymore. I've been working on myself ever since, but he still haunts me and apparently is continuing to talk crap about me to people.

What am I supposed to do with that? Live with it? Should I confront him calmly and tell him how it makes me feel? We hang out in the same circle of friends and I'm not the person that he is making me out to be. :(
<bot>: Ran into ex, overheard him talking about our bad break up to another girl. I can't really escape our break up since we have the same circle of friends.
