I think for most of us, relationships do change with the weight loss. My situation isn't as bad ad others, but I have noticed that my relationship with my significant other has changed since I had surgery. He was super supportive of me having the surgery, and even went to the pre-op classes and knew what I was going to be doing for the rest of my life, but somehow it didn't stick into his head after I had surgery.
From the first day after surgery, he was already getting upset with me because I didn't want to share his drink, or even share his dinner with him ( he likes to share). He doesn't eat the healthiest, so most of the stuff he wants to share he cant have. Once I was able to eat solid foods again ( about 6 weeks) he is constantly arguing with me because I don't want to share what he is eating and he doesn't get it through his head that I cant eat that.
So after all of that, our relationship has changed. I am not the same person I was 6 months ago, and I am almost certain that he is insecure and is scared that I am going to leave him. I have lost a significant amount of weight, dressing nicer and stepping up my game, getting noticed in public, and going to the gym a lot more than I did. At first I kept telling him that I am with him, however I am slowly noticing that I am drifting myself way from him. I am not doing it on purpose, but I am doing things to better myself and he is doing nothing to showing that he wants to do better, except for complain that I am doing too much. I am going out more with friends and being active because he doesn't want to.
I finally had to tell myself, after being told by him that I am done losing weight, ( yea right! I still have more to go), that I am doing this for myself and he wants to go on this ride with me he can, and if not that is okay too. I kind of expected this to happen and if we stay together or not, I can say that I at least put an effort and am not upset if I lose him or not.
