I urge you to get your OWN therapist and start doing your own therapy. You have a window of time (biological) to work within and while there is plenty of time now, the years will tick by and your window will close.

The decision is - do you want to spend years waiting to see if he changes his mind or do you cut your losses here and use those years to find someone who is eager to have children?

Your posts talk in terms of "we" but it sounds to me like HE is driving this train. How would you feel if you waited another 5 years or so and found out that you require expensive interventions to try to achieve pregnancy and you couldn't afford it? Or you wait years and you're 45 years old and that window is closed? You need to work on THAT basis - not the basis where "we" love each other and he shouldn't let mental illness stop him.
