What if your whole relationship was a lie

Ok so my bf and I have been together for 3 years I dealt with a lot of trauma but I can’t ever seem to not love him or not want to be with him or be around him. For 3 years this man has consistently cheating non stop it was like all he cared about was chasing pussy excuse my language but that’s all he was doing. I been through a lot and sadly I’ve had plenty of women come forward saying they’ve slept with him and or they e texted back and fourth and didn’t know he had a gf but he clearly did. My question is after multiple affairs can a relationship be the same again? Because I’m not going to lie I’ll never stop thinking about it and scared I won’t stop bringing it up! Idk what to do or how to feel
