First, is there ANY chance of you and your husband getting back together. I'm going to suggest marriage counseling. Counseling can help you two learn HOW to communicate. I totally understand the fear of saying anything for fear it will be taken wrong, or that you might say something you don't mean. Counseling can help you with that. If you two are willing to go to counseling, perhaps this marriage can be saved. Do you think your husband would be willing to go? And are YOU willing to go? It WOULD help.
Secondly, as far as you -- check with your local county health department's mental health -- they MIGHT have counseling services for you and a very reduced rate, or even FREE. It would be based on your income. You would be well served to go to counseling on your own. Check into it, and see what they have to offer -- I know you won't regret it. If they don't have anything, I KNOW they could tell you where you could go for reduced services.
I wish you the very best. Please let us know what happens, will you? God bless, and please take care. Hugs, Lee
