It can certainly survive, but is that enough?.....If I were the wife in question, I'd want to know why my husband doesn't find me physically attractive. In my own marriage, I've been 20 lbs up and down on many occasions....(and I didn't feel too great about myself when it was the UP)...but I must admit that my hubby still desired me regardless......I can't help but wonder if more isn't going on here? good luck...grace
