<human>: Me and my girlfriend broke up a year ago.  The break up was messy, and we kinda both got depressed and angry at each other for a few months.  I was far away at the time, so we havn't seen each other since.  We both had a plan by this time we were going to move into the same house and go to school together, we didn't move in, but I'm in the same school right now. 

When we both broke up, she found a new boyfriend really fast and I was pretty upset at her for the first 6 months, and It was really annoying what I was doing...I stopped messaging her since, until last week where she liked one of my status's on a social media site.  I messaged her "I'm not here to interfere with you and your new boyfriend, I just want to go to school.  If you want to meet up so we don't have to fear about running into each other, it might be a good idea"  So we met up twice, and I think it was okay.  I think she's been kinda a jerk to me though? It's annoying but I'm not gonna do anything.  

Here's the situation.  Her new boyfriend is a fighting enthusiast, with a black belt and training a bit.  I'm kinda scared if he wants to pick a fight or something, cause that break up was messy.  I usually stick up for myself, but I don't know what to do.  I usually wouldn't turn down a fight, but I don't think I can in this case, and I don't think he likes me anyway. 

I'm not sure what to do. :/

Can you give me the gist of the text in a nutshell?
<bot>: My ex's new boyfriend is a fighting enthusiast that probably doesn't like me...and I'd like to avoid conflict, but I'm not sure what's gonna happen.
