Ahh... I once experienced this sort of domestic violence with my parents. They fought a lot with each other quite violently a couple years back. They're good now though. Trust me, I know the emotional and mental toll that can take on a kid.

It happens.

Oh, and regarding your last message, there's this old popular saying that goes:

Its always best for a couple to go through Family Planning before starting a home. Think of your future, think of your kids.
