He sounds good right now but it only has been four months since his new look. I suggest giving it time and seeing if it lasts.

If he could afford counseling for himself perhaps he can help pay for yours. It is because of him that you need it.

I imagine that you can’t forgive him yet because of the magnitude of what he did to you. Forgiveness often takes time. And the more healed you become (e.g. through counseling) the easier it will be to forgive.
