Cheating, and staying together?

This is very hard for me to talk about especially to the public, I just want unbiased feedback and advice... so the beginning of college, I started dating my boyfriend barely two weeks after school started.

Unfortunately, there was a pattern of cheating from him ever since the beginning. It started with him having sex with his ex not even two weeks after becoming exclusive. Followed by sexual encounters with 4 other women.

Finally, after the 5th time, I decided to break up with him. It was very traumatic, I had gone to his room, found him there in bed with another women, and had to break up with him through the door because he would not face me.

Exactly a week later I was having fun at a party with another guy, just dancing then he kissed me. My ex saw and immediately went back to his dorm and started sobbing and having a panic attack.

After the party, I realized what was happening and gave in, went to talk to him for the first time since everything happened.

I gave it some thought, we are dating again, however, I do notice a change in the relationship and in him but I can’t get over the fact that we he managed to hurt me so bad. I constantly compare myself to the girls and beat myself up for his mistakes.

I forgave him but I will never forget. I wanted to reach out to you guys and ask if there was anyone who has been cheated on and managed to keep a relationship after. How you did it, and how you regained self confidence.😔
