What should I do about being called ugly by the father of my child?

The father of my child called me ugly in front of people. I know that I am ugly because many people have called me ugly before, but hearing it coming from him, worse, in front of people hit me so bad.

We are still together. We were okay until he cheated on me while I was pregnant. He cheated on me, not once, not twice but more than 15 times with different girls. We broke up and got back together about 5 times.

Whenever I leave him, he loses focus on everything and becomes so depressed and lose weight. He was once admitted to the hospital due to depression after I left him.

When I’m with him, he sees other women but when I leave him, he dumps them and becomes miserable at home. He apologizes and then I take him back. And then two months later, he finds another girl. When I dump him, he dumps her, just like that.

I think I have accepted that men will always cheat. I have extremely beautiful friends who are even educated but their partners cheat like nobody’s business. So I’m always like if they can be cheated on like that when they are so beautiful, then who am I not to be cheated on?
