Am 47. Have 3 dc who are 10, 12 and 14 and a husband who is 12 years older than me. The only physical affection I get (and am able to share) is from my 10 year old.
H does not touch me EVER on a day to day basis yet is very cuddly with dd2 (10) and always trying to cuddle dd1 (12) as well as telling her she is gorgeous and cute (which she is but it is strange being a witness to all of this but being outside it, and thinking that once upon a time he used to feel like that about me 
).
Sex happens only if I initiate it and with very large gaps in between as H is not interested.
I am about a stone overweight (aiming to lose that over the coming 7 weeks if possible) and feel boring, sensible and invisible.
The possibility of flirting with anyone or anyone finding me attractive again seem to have gone out of the window .
Is this what the middle years are like ? A slog with no romance or even being particularly liked to liven them up?
