survivinginchicago is right on, Emily.

You just keep pressin' on with YOUR life.
Kevin either will clean up his act (which WILL require professional help) or he won't.

It makes no difference what you do.
He has to take responsibility for himself.

When he hit you, he changed everything.
You can't "stand" for someone that is dangerous.
It's just not that simple.

And you are not expendable.

You have to save yourself.

And if you don't mind me saying, I think you're off to damn fine start!
