But yes I do love him more than the OW, and have tried everything to fix our M, to the detriment of my health, some friendships, my job and my self esteem.
Read this sentence out loud to yourself.
Now ask if any of your friends told you this, what would you think?
And then ask yourself, is he really worth losing when it costs you your health, friends, job, and your self worth.
I don't mean to be rude, but it seems like you don't want your husband back. You want to prove that you were right in forfeiting everything just so you can say you were right.
That's not love. That's pride.
You are sacrificing your health for a man who doesn't want to be with you. You are paying for your stubborness with your life. He's not worth it.
