He cheated, lied, abandoned, stood me up, and completely ignored me for more than a year. Why is he calling?

look at your question,why?? why not ? u came running each time. ur feeding his ego. he needs to prove to himself he has u where he wants you,and by ur actions he does. he doesnt care for you at all.sorry.hes a user and hes caught u in his web. Climb out ,shake it off and put him in the past. you dont even need a friend like that. Well a friend wouldnt do that so i wouldnt even say he was a friend.
