Hope you have a lot of life insurance on this guy for the childrens sake. Just because he is trying to have a heart attack doesn't mean he should take you with him.

You know what is amazing to me is before he moved out he ate what I cooked and dropped 40lbs in a couple of months just by my changes. I've always thought of him as being supportive before he moved out. If I think about it too much I get confused and frustrated. I'm realizing I can't worry too much about him and his choices. Food or anything else for that matter. Hhmmm.
Thank you.

Wow - isn't it great to have a place where you can find friends who are willing to kick yours OR his OR yours and his. 
3 pounds...think how far you've come and you can change that to "just 3 pounds" and know that you will do it.  We all know that you can - and the surgery will help you take off even more! 

You are worth it...  Him...maybe - maybe not, but YOU are worth it!

I don't know the details of your separation, but is it possible he is scared of losing you?

It is hard on husbands somtimes to have the thought of thier wife looking better through weight loss.... Particularly a wife he might be losing anyway.
