You assume that the only thing of value to me about my partner is his physical looks or that weight gain would automatically make me unnatracted to him.
Neither is true.
I was not referring to you and your partner. I was speaking hypothetically. Men are visual. I was asking what if a man is NO LONGER physically attracted to his partner due to her weight gain and she refuses to try to eat healthy or work out. What if her physical state no longer physically excites him? It's a real life hypothetical situation, how should they work through that if her current looks do not excite him
