Hello and welcome acrazynao,
Rhiannonsmoon made a couple of very good points. 1) People are different in how they react to medications and therapy. Very true

and 2) This site can be very helpful. Many, many people share their experiences and/or knowledge to help others through. A great resource!
I'm not sure that I'd agree with your husband not wanting to work through T with you. It's complicated. When is it never complicated? LOL!
I've been in therapy myself for many years ~ just trying to fix myself. I have seen many different T's, and can wholeheartedly tell you that different T's are better for different people. Perhaps your spouse didn't feel a "click" with this T? Perhaps he felt that the T spent more time doing ___ than they should have and not enough time discussing other matters. Just possibilities for you to consider.
Personally, I've also become divorced. First, we separated for a year. When we couldn't quite click even on "little topics", we could see that we were at the end of our road. It is very depressing to me. Not an easy thing for me at all. I often wish that we had tried harder back when we still could make a big difference. Back when we were honestly emotionally committed to one another. My ex and I have been apart for 2 1/2 years, I think, and it still makes me so sad. (Us having children together requires very regular visits.)
I'm not trying to bring you down deep into depression ~ Gosh, I hope that I didn't! I just want you to really think about the changes. Remember when we took our vows? Does that make you feel a longing, sadness, anger, or ??? Something to think about. Talk about those emotions and thoughts with a professional, to help you through in understanding yourself. Go from there in what you feel the right thing to do is. You do have time.
I wish you the very best ~ take care!
