Most Helpful Girl
What you are experiencing isn't love, most women are attracted to "players" and "badboys" so obviously you don't have sincere feelings for him but rather a strong attraction towards him. This means that you will get over him in no time and that if you stay away from him you will one day wonder why you were ever attracted to him.
If he calls you again, I think you should simply say "Hey, I am a bit busy now, gotta go, bye" just like that. But you have to remember to do this every time he calls, so after a while he will get bored and leave you alone. :-) hope it helped
