My husband keeps saying that 'we' need to lose weight to become attracted to each other again to save our relationship. For the record I have never once said I don't find him attractive. I still do but apparently he doesn't find me attractive enough to initiate sex. He said he can't live in a sexless marriage. I am a UK size 18 and pretty sure plenty of men would have sex with me looking like I do. We have a 4 year old daughter and I do most of the looking after so I don't find it easy to find time to look after myself. Am I being selfish by not losing weight?
