Rapunzel,

From what you have said before (in another post), I think you said that he is quite controlling and has a temper.
And at the time you blamed yourself then, for his actions.

It could be that through therapy you have learnt why you married young, and why you picked him.And now that you are "growing",have realised that you don't need to depend on him.

I don't know how far along you are in therapy.
If you have not been in therapy very long then it is not best to make huge decisions until you are near the end of it.

As for the children, they would want a happy Mother. Don't stay in an unhappy relationship for the sake of the children. Children can sense when things are not right.

Hugs to you.
