Not sure I understand the question. if i was less attractive to him then he would not have initiated a relationship with me to begin with or married me. People generally get together based on a mutual physical attraction among many other things that factor into why two people like each other.
or do you mean if a woman suddenly gains a lot of weight or grows a beard or something ?
sameHe married me when I feel like I was less attractive so I think he would deal.
Love me, probably. Although realistically some resentment can kick in if one partner really lets themselves go and the other doesn't.
Sexual attraction not so much.
