I liked the Guardian comment that said "Instead of giving her HRT, the doctors should have given her husband bromide."
It is one thing to feel upset (as I did) by the loss of libido which happens to some women after menopause (I felt like something important had died inside me) and to want it back for your own sake. I take HRT and am very glad to have my sex drive back. It is quite another thing to be coerced into it through emotional manipulation.
There is also a huge difference between on the one hand feeling, reasonably enough, that a marriage without sex is a marriage in name only and you want out, and on the other hand keeping all the social and domestic benefits of marriage while screwing around like a randy terrier.
This man isn't a poor, put-upon soul who felt emotionally bereft by a sexless marriage, he's a serial shagger with no redeeming features.
(Also, as an aside, sometimes people do decide to live in a sexless marriage due to physical changes - and it's not always the woman who can't have sex. Impotence is a very common after-effect of treatment for enlarged prostate/ prostate cancer. As an elderly relative of mine confided, yes, she missed sex enormously, but after a long and loving marriage, most of which had been very sexually satisfying, but this was just in the "for worse, in sickness..." bit of the vows.)
