Hello Dawn ~ well, it sounds like you are in quite a predicament. You have obviously been through a lot. I don't think 'mother nature' wants you to have children.
It's your body (and your sanity) so please don't let anyone "talk" you into having a child ~ that includes adopting, BTW.
If you 'have a child' for your husband, you may resent him and the child for the rest of your life.
With the paternal instinct that your husband obviously has, he could join the "big brother's association" to fill the void. There are a lot of needy kids out there that desperately need the 'father figure'.
Be strong and don't try to please others. It doesn't work. Think about what would happen if you did adopt, and you and dh split up again ~~ guess who would be left raising the kid ~ the one who really didn't want a kid in the first place.
Please keep us posted. I wish you all the best.
Regards,
cp
