It happens a few years ago, after been in the relationship going for 2 years, in which she show herself like a high jealous person, like, "Who you talking with on the phone?" (everytime i got a message) "How has been your day, how many people have you seen, and who were those people? What you talked about?" (almost everyday I got home from Uni) and the subsequent fight, with cries, reproaches and anger because of the jealously, after a relative calmed summer, when we have to go again to the circle Uni-jealous-fights, I started to lie to her, on things related on my social life.  


Things like i wasn't talking with my friends on uni, not going with them to class, not meeting at lunch, not talking with anybody on whatsapp, facebook, etc. This continue through the whole year, until she find out by looking conversations at my phone.  


She confronted me about it and I started by negate it all, but she won't let it go, so after 3 weeks i finally tell everything, at least the things I remembered, because she wanted to know all the small details. And when I mean, all, is ALL. In any case it involved cheating, sex, flirting or any of it.   


After that I wanted to split up, but she wanted me to fix "the problem" i have created, but I always thought it wasn't entilery my fault, so I didn't "make up" for it. Recently we broke for the best.  


So who was in the wrong here?   


TL,DR GF is jealous of my friends of uni so we got in a lot of fights, I decided to lie with whom i pass time during a whole year. She discover it.
