Breakups/cheated on/done with guys

Well today my boyfriend broke up with me and I said why we been together for 2 years and you know what he said? He said that I'm not pretty I'm ugly fat stupid and just a plane dumb bitch. And when he said that to me I got so upset and just slapped him in the face cuz I hated that so now I'm thinking I don't want to be in any more relationships cuz it's painful and sometimes just to stressful. So should I just not be in relationships or find a nother guy idk what I should do any advise girls please?
