<human>: I was with this girl for a year before I broke it off with her. The relationship started out great like most but slowly things became really sour. She's originally from a different country from the one we're living in now and here on visa. 

I started to notice throughout the relationship she'd have fits of rage when ever we fought, like almost like she couldn't control it and became a completely different person. 

I first noticed it about 4 months into the relationship when we were at a party and I got pissed off when she flirted with another guy right in front of me, she took it as me not trusting her and we got into a fight, next thing she breaks up with me at the party to prove a point of how ridiculous I am being (stupid I know).

After that it came in phases of getting into a big fight, making up, being happy then building up to the next big fight.

Sometimes the fights we're REALLY bad, there was hitting, pinching, calling me names and just destroying what self esteem I had left in those moments.

Then a month ago she told me she made out with another guy and thats where things went WAY south.

I've only recently gotten the courage to break up with her and I'm staying strong but I just have huge waves of guilt from her, she still contacts me telling me I'm the only one for her, I'm the only good thing she has in her life, shes all alone now, why would I do this to her, things will be different, why cant i give her another chance. But at the same time saying she supports my decision.

I'm just feeling constant guilt for doing something I know is right for me and I don't know how to get over it. I still see her as my best friend, don't get me wrong all the above is the bad stuff, there was really great times too but in this case the bad out-weighed the good and I couldnt do it anymore. Any advice would be great.

Give me the gist of the text in a nutshell
<bot>: Ex-girlfriend is making me feel guilty for breaking up our relationship that wasn't healthy for me and the guilt is now making me feel worse than the relationship.
