He cheated and I cant forgive him but should i provide a second chance?

My boyfriend who I dont want to call my boyfriend created a different snap chat to speak to girls, ask for nudes and flirt. When I confronted him about it he said he didn't wanna lose me and wanted another chance, he also admitted that when he did it he wasn't thinking of me. Me being dumb, I gave him the opportunity to explain himself and hes been acting so different, taking me to places I want to go to and to listen to etc, things he wouldn't do in our relationship, i feel blind to this, I dont know what to do, im obviously still to hurt to make the decision
