Oh, yikes.
Men seem to really be threatened by weight loss, for some reason. My husband was threatened when I started this and lamented the loss of my boobs. He made me feel awful there for a while. We finally had it out and I got him to understand why I was losing weight and that I needed support and not constant criticism. Unfortunately, I AM leaving my husband now and it has NOTHING to do with weight loss, but guess how the rest of the world perceives me.

It certainly appears as though I lost all this weight, gained all this confidence, and look...now I'm leaving him. Whatever. They can all believe what they want. Being morbidly obese is terrible and makes everything about life so much more difficult.
Stay strong. Please ignore his behavior. He is scared of losing you, obviously, but just remind him that right now he risks losing you in a much more serious way. Your health should be his number one concern for you. What if you had breast cancer and had to lose both breasts? Ya know? We are not our bodies.
