I'm so sorry that happened. And I know how much hurtful words from your spouse can really shake one at their core. Could you find a marriage counselor who does online video calls? I think therapy is the only viable option to get to the root of what's going on. Or maybe a bariatric surgery support group for partners. Someone had mentioned that he may feel threatened by your weight loss. That is not an uncommon problem; especially if the partner is insecure. Maybe try to build up his security. Men normally respond to verbal praise. For example, in the first few weeks after my surgery, my husband was a very grumpy person to be around. When I commented on it, he blew up and said how overwhelmed he felt with work, taking care of a large portion of the home responsibilities, that it's been all about me and my recovery, and a few other things. I took some time to process, and in the right timing, I thanked him for all he's doing and told him that it did not go unnoticed. I reassured him and built him back up. Since then, things have been going really well. Your therapist may have some other ideas.
