There are alot of things in your situation that make me go "oh no" but none more so than you agreeing to giving up your want and need to have more children.

Do not do it. Even if everything else gets resolved and becomes better that is one thing that will always play on you and you will eventually resent him for it.

You do sound like a strong person, you are just easily swayed by someone you do love and he knows what buttons to push to make you feel that way.

Take a step back to 7 months ago and remember those feelings that made you think I cant do this anymore and hold onto them. When you feel yourself getting sucked in, read and re-read this thread.
You are a strong person dont let him think your not!
