There's so many good people in this world who stay with people who treat them like shit. And I was one of them. From both sides. I've treated people like shit and I've been the good person who was treated like shit. Why do we do it? And why do people treat the one person who takes care of them like shit?

Found a convo where my ex (26m) of only a week was telling someone they were just using me to not be lonely and because I'm a good cook, and more stuff. A few days after they said they love me so much and I would make a great mother. Here's some of the things I got today:  

"I had already forgotten about you until you emailed me. We don't have a history anymore. I feel sorry for the next douchebag you go out with. God help him.  "  

"What you see now is a real bad person. Too bad you couldn't appreciate me before it came to this. "  

"Imagine if I had been dumb enough to move. Jesus Christ. Go fuck yourself. " (I was the one who left my family/friends to move to him)  

"Quit your emo bullshit. Also, next time throw my shit away. I'd rather you not come near my apartment. " (I left a small box outside his door with his boxers and a model plane he left at my place, and I had just told him that I hope he finds someone amazing after me, not being sarcastic)  

I cooked several times a week.. I supported them.. I tried to improve our sex life.. I did everything that I was capable of to give this person a chance. Wasn't perfect, of course, but damn I tried my hardest against all the odds.

I just want to find the person who won't treat me like shit, so I can not treat them like shit back, and we can have a happy life.
