Hello and welcome!
First of all, it is great that you have put so much thought and effort into this! Too many people have rushed into marriage and paid for their haste in one way or another.
Here are some questions that I think you need to ask yourself:
*Has he, or is he willing to go through treament for his disorder. This is something that can be largely overcome!
*To what extent is he able to be around others? Would you be housebound whith no social life at all? Or would it simply be somewhat limited to a small group of friends that he is comfortable with?
*Everyone has challanges/limitations/issues. Is this one a deal breaker for you? Or is it worth the hardship that this may present to be with him?
*Is he adamant about not wanting children? Is this acceptable to you? Or would you grow to resent never having children if you were to stay with him?
We really can't tell you one way or the other what your decision should make of course...but thinking on these questions may help to steer you towards your answer.:)
Please know that you are both welcome to post with us here anytime...we are here to listen, care and support!
Best Wishes,
