Part-Time Dad

I was the first born out of your two kids,
he's not addicted to drugs or has a drinking problem,
he's addicted to leaving,
leaving me
he was there when i was born, then lefted because he had gotten arrested,
came back played mom,
lefted again and now he's back.
I'm so confused because i don't want a part-time dad i want a dad that is going to be there always, not come, leave, and be back.
what is that?
i want my dad in my life not in and out
i justed wished i didn't have a part-time dad!
