Weight loss and relationship

I started dating my gf when we both were obese. We wanted to lose weight together but I have lost almost 100 lbs but she hasn’t lost much. She’s on Ozempic and I’m not but she still complains how she can’t eat as much as she used to if she wants to lose weight.

I’m trying to help her. I do all the meal prepping and I have told her I can meal prep her lunches as well. Count calories and macros but she wants eat lucnh with her colleagues eventhough she knows she eats too much.

We were in this project together but this is more my personal project now. It makes me frustrated and even question my relationship. We are in open relationship and I know I attract women now. I went from being obese to strong dad bod. (I’ve lifted weights for years.) Nowadays I’m competing in brazilian jiu jitsu and have stereotypical heavyweight physique: some gut, broad shoulders and more muscle than average guys have.

My weight loss makes me question my relationship
