A friend of mine said his wife became disinterested but had a huge
collection of romance novels she read all the time.
Maybe a little romance would go a long way.
I asked him that and he said he didn't know anything about
all that romance stuff.
I then pointed out the fact that there are about a million books
on the subject and maybe while his wife was reading he could
do a little reading for himself.
I think he went and turned the game on instead because they
got a divorce not long after that.
Not saying that is the general answer but in his case I think it was.
