Thank you so much for your replies, feel much better to even know that someone can understand how I feel. My insecurities are my own problem and this is why I am following a therapy. My main problems is, I suppose, the fact that my OH himself is a health professional (and one of my DDs) and he hates it when I talk about my personal insecurities and refers me to my therapist. So, now, I just keep my dark thoughts to myself (well I do share with a few friends and of course my therapist). I make myself feel ugly, etc....
What doesn't help, I think, is that my OH is not very demonstrative (or should I say, not at all). I have talked about this with him and his reply is: well after so many years, why should you expect me to be different now?
I think that deep down, my problem is : a) hormonal, b) depression that rears its ugly head from time to time and c) just need a cuddle from time to time and know that I not going to get it....
Intimacy is getting rarer as we get older but tends to perk up during holidays (which are regular) so can't really complain, but then again I would definitely prefer more of it .
OH is a terrible flirt, even at his age (mind you I suppose that I am too, from time to time) and I think that as he doesn't have any insecurities (that I know of) this also makes me feel, how can I say, in doubt.
I don't think that I have any valid reasons to think that he would do a runner, I think that he would prefer to have a piece of cake (eventually) but not to risk losing his peace of mind and living, plus all the hassle a separation would cause.
I am very close to our children and grand children and I think that he would be, even gently, pushed aside, if you see what I mean.
Anyway, being able to type all this out has helped me put my thoughts straight and I will defintely have a good session with my therapist.
Thank you all for your comments. Getting older is not always easy. Losing your "force de séduction" is very depressing but being a mutton dressed as lamb, even worse.
Forgot to say that I still work full time, so am not at home all day being a pain in the bum.
Have been lurking for quite some time and needed ages to pluck up and post.
Thank you again
