A man who doesn't spend time with his children and who doesn't make his children a priority is not a good dude.
If you end up having a child with this man and you're upset at the lack of involvement he has with your child I will SIDE.EYE.THE.HELL outta you cuz you had pebbles before you were hit with that brick.
Oh...and calling his child once a week doesn't cut it. Da hell a phone call gonna do? Go see that kid. Pick them up and take them somewhere. Help them with their homework. Hit up parent teacher conferences. Play basketball, baseball, whateverball.
Children require far more than just money to be raised.
Oh...and if you over there laid up like a pron star with some dude all the time knowing he hasn't seen his kids but you see him all the time...guess what? You ain't shit either.
