Hell, my dad only gets to see me 8 hours a week (168 hours). Think of how your kids feel, not being able to see their father. In my case, my father has dealt with addiction, which has set him back, but if a father has stability, they deserve the right to raise their child. Sorry if I rambled on too much but I just had to type this.
Fathers also hate being separated from their kids and vice-versa. I only get to see my dad once a week and its hard not having your father with you at all times. Fathers are parents too and need to be seen as equal.
