I'm worried about not finding my wife attractive post-gastric bypass surgery
Thats a shame. Is this due to her having gastric bypass surgery?
Kind of, her attitude has changed
You should love your wife no matter what happens. If you have problems it might be good to go to couples therapy.
Uh. That's how the world is. When people lose weight, they are more attractive.
Life after Gastric bypass can be difficult. Husbands are expected to be there for their wives and support them through tough times. Even if she becomes more attractive that doesn't mean she will love you less.
