I am very sorry he is not supportive of your condition and is distancing himself. That must be very hard on you. I like the suggestion to invite him to one of your therapy appointments - he could learn a lot more about this that way.

Thing is, you are exactly the same person he agreed to marry, before he knew about this. Nothing has changed except a proper diagnosis. And now that you have a specific diagnosis, you can be treated properly for it with the right medications and probably will be better off. He needs to understand that nothing has changed between you or about you at all. He may just be scared of the unknown and what this means for him as well as for the relationship. (((Hugs)))) I hope things improve for you two.
