It's not WRONG for you to WANT to stay, and I completely understand how difficult it is to leave, especially with two children. The problem is you will be facing and putting up with abuse. And most likely he will hit you again. Abusers do NOT change.... or rarely do, and not without therapy.

So it's your choice.

You will most likely face a lot of problems and it will wear you down after a while. That's what abuse does to a person. It breaks them down, it breaks their spirit, their soul and it harms their self esteem.

You also will not be doing your children ANY favors by allowing them to grow up in an abusive family or home.

It is not healthy role modeling, so it's going to harm your children's healthy development. Again, that's your choice, but understand the harm that you will be inflicting upon yourself and your children by staying.
