Am I stupid?

So recently I found out my boyfriend of almost two years was cheating on me with multiple women the whole time we’ve been together and he also thought about getting back with his ex while we were dating (text messages I found between him and his friend) and he’s been begging me to give him another chance to prove himself to me. He also had bit of a drinking problem and would lash out on me. And all throughout our relationship he was very jealous about any guy I knew and he would always think I was talking to some guy and go through my phone and delete guys From my social media. I loved this man but I don’t think I can get hurt all over again. Am I stupid for giving him another chance? I just really need help through all this.
