I need some উপদেশ on an absentee father.

*deep sigh* আপনি see, my father hasn't been in my life most of the time. I lived with him up until I was ten months old, but then something happened (something chaotic, all I can say) that made him hand me over to my grandmother and step-grandfather. I lived with them for a while, and after some time my mother left rehab and lived with us too. From the ages of eight to around nine অথবা ten, I would see my dad and my half-brother on weekends sometimes. But then came the night were my dad started drinking (again), and he ususally got violent when he drank. So I didn't see him after that.

The last time I saw him was when I was ten and he was with his girlfriend and my then baby half-brother, Zvi.

I think I called him one time, but..well, it didn't go well.

I haven't heard from him অথবা seen him since, until just fifteen মিনিট ago.

My mom told me that he called after she took him to court for Child Support. She gave him a picture (he thought I looked like mom --EEEK!--but everyone says I look like my dad, but anyways), he called and told her that his grandmother (my great-grandmother) died, and he wants me at the funeral. Should I go?
