Me & my ex boyfriend problem...?

Well Me & my ex was going out for 7 months off & on.. but i really hurt him really bad because i cheated on him and i didn't mean to or wanted to.. so he said he was crazy in love with me until he found out about that other boy. he said he started falling out of love with me lil by lil.. and we broke up again because of the way i would act.. (jealously, attitude, mood swings etc.) so right now he saying he still have feelings for me and earlier today we was all hugged up.. can somebody tell me how i can get him back and have him be crazy in love with me again ? Pleasee :(
