No advice to give you, my friend.
I have not had that experience.
Just a prayer for guidance for you, and an admonition to not give up.
Sounds like you haven’t discussed the situation with your husband. Probably won’t go away on it’s own so it has to be talked about sometime. You owe it to both of you, and your kids.
If face to face is intimidating for some reason, how about a gentle note with a flower (or a strip of bacon)?
p.p.s NEVER ask your husband “Am I too fat?” (or anything like that). Normal guys will not want to say “yes”.
Instead ask husband something like, “Dear, I would like to get a gym membership and take some exercise classes.”
that is a better way of asking him if he would like you to take some weight off.
Weight is easy to gain, very hard to take off.
