I can’t image feeling this way. I really just can’t.
My husband watched me go from the picture of perfect health, and looking like that, as well – to a very sick, bald woman. I went from an active runner, with a very fit body, to a pale (sickly pale) woman, that was very underweight. When my hair fell out, I was sure I would disgust him. Instead, I was told how beautiful I was. I was also told that I was the same person he fell in love with, just with less hair.
There was a point where I think I became more of a patient to him, than a wife. Never, though, did I feel that he stopped loving me. There was a point where it seemed like our intimate side wasn’t as strong, but then again, cancer doesn’t leave one feeling great. However, it was very temporary.
If this happened to me, where I started to lose interest, I would have to do what @Simone_De_Beauvoir said. I would need to examine the reason. I hope, though, I would never be in that position…especially considering what we’ve gone through….for several years.
