Is it me or him?

I started messin wit this guy in late july. when we met he was so charming and he still is but i see little things that are changing. like he use to call me all day around the clock and now he calls me around 1,2 o'clock in the morning. thats something i think i should put i stop to, but it so hard to because of the feelings i have devloped for him. then last night i got a call from him saying that he loves me for the first time. i think thats because i found out about the other woman!!!!!! knowing all this i still cant let him go. but deep inside i want to. what is it me or him???!!!!!
