I hate that men (who are fathers) can easily say "I don't care to provide the level of care our child needs" and head off on vacation, or dates, or whatever else they feel like doing, whilst leaving the child's mother entirely responsible for doing it all.
I also hate that (some) will think that throwing money at a problem is the best way to fix it. Kids don't want money. They want to feel loved.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
