My biggest mistake was staying in a 2 and 1/2 year relationship with a guy who constantly cheated on me.

One time, there was this girl in his class, they were too close to be normal, He wanted to invite her to a kickback but I told him not too. I even told him I had a bad vibe about him and her, he kept insisting he wasn't interested in her and what not. He invited her anyways and insisted that me and her will be "really good friends" So he even introduced me to her. When I was talking to her she was surprised that we were dating, she asked me about it and told me he was telling everyone he was single. ( We were already 2 years into our relationship ) Afterwards when I left, my homie stayed and it turns out they were playing footsie, was holding hands, kissed, and even made out and shit after I left the kickback. This wasn't the first time he cheated on me, and it wasn't the last.

Apparently, according to him he wasn't even actually attracted to her, he just wanted to "feel something". So I brushed it off, since I don't blame him for how he acted, he kinda grew up in a really weird environment where that kinda shit was normal and what not. Stayed for another half a year. Costs accumlated and ended up blowing thousands of dollars on him throughout the whole relationship. Never got much in return.

I believe cheaters can change, and I still do believe this. But apparently, fuck boys can't.
