Continuation on previous question about dad?

Okay, this is continuation of my previous question.. please read it otherwise you won't have the required details to answer; my dad didn't called me for about 40 days and today he called me on the phone about 30 times but I didn't answered. I hate him about that he cheated on my mum and left me, but still I feel sorry for him and I'm afraid he could commit suicide... please help/
