Well girl you are gonna have to decide for yourself, everyone is blinded by love especially females. Even the ones that say they arent dont know it. I was once like that too, my bf (baby’s daddy) cheated on me many times, the first time i went back to him because just like you i thought he changed just because the way he would talk to me, he even started crying once… but behind my back i later found out he was cheating. ONCE A CHEATER ALWAYS A CHEATER some people think that is just a saying but if he has enough guts to do it once it will happen again. I know what a broken heart feels like and yes it hurts very bad, if you dont want to go back to that then you need to open your mind to the truth… maybe staying friends would be the best because then you cant get hurt! Good luck girl, dont be one of the stupid ones who regret it in the end like me
