As title says i got cheated on by my soon-to-be ex 3 times and every time it happened i broke up with her but after some time came back together and she always preached that she changed, to be honest now she seems like she actually changed but i just cant build confidence in her anymore.

Some background, we were highschool sweethearts and best friends and we have been together for five years on and off, she never had sex with another dude but she kissed them. 

To be honest, i mainly think i keep coming back to her because i cant make my mind comprehend that here are actually better women out there mainly because im not the best guy when it comes to seducing since i dont have much experience.

Right now, I told her that i wanted to talk to her tomorrow and im going to break up with her but i need some advice on REALLY get over her cause im done with this, its an unhealthy relationship and it fucks with my mind.
