He has changed, the relationship has changed. I think you are obligated to give it a try, but if it does not work, nobody will think less of you if you move on.

Of course it's ok to stay. He is still your fiancé and will still love you.

If you want kids you can still have kids. I have a mentally handicapped uncle and he has two wonderful children and a wife that loves him.

Being handicapped doesn't mean someone is any less worthy of love, if you were in an accident and became handicapped just imagine how you would feel if the love of your life left you...

The only difference between being a fiance and being a wife is the formalities. You already agreed to the "til death do us part" when you agreed to marry him; only the law sees it differently.

Watch "The Other Side of the Mountain" - a true story available for streaming on Netflix - and see how you feel about leaving somebody you were engaged to and is now facing an uphill battle.
