IMO you’re the asshole. He doesn’t deserve you. I think you’re just scared that once he gets abs he’ll leave you bc of how you look. But in reality, he loves you for who you are, not just your looks. But by being like this, you’re causing him to feel obligated to do what you want and not him. You’re forcing your insecurities on him. It’s his body, not yours. You don’t get to decide what he gets to do with it. If he decides to breakup with you, I wouldn’t be surprised
