My little sister let's call her Clair and her ex had dated for 4 years. I hated him so much. I used to punch him every time I saw him. Until today. It went from punches to hugs. Now we are friends. And I kind of like him and I don't know what to do. HELP ME PLEASE!

Well, let's say "Clair" would find this out, she would probably be oversome with joy, now that you two are friends, the question is, "How" did you become friends? PokeXpert

How long has it been since your sister and he have broken up? Did he break up with her or she with him.
How old are the two of you?

She's your little sister, you don't want to hurt her! If I were you I stay away from him!!

Personally I would not date someone my sister dated. It's just bad form.

You kind of like him? Then walk away now and don't look back. Before you really like him.
