I don't know, OP. I'm 40, single and I don't think it will ever happen for me now. For many reasons, I've never been loved and I wouldn't recognise it if it bit me on the bum now...
Besides, when I do go out, the behaviour of men convinces me I'm better off single.
Last night I went out for a drink to a quiet, backstreet real ale pub. A couple came in and I noticed them straight away because she was like a younger, more attractive version of me and he was my type. I caught him looking at me a few times and on the way back from the bar, I looked to see if he were looking and he was. And rather than turn away he held eye contact until I'd passed.
Whilst he was sitting opposite his very lovely girlfriend. And I certainly wasn't smiling or being flirty.
That's the reality of being in a relationship for me. Feeling like like I have to compete with every other woman on the planet when I'm sitting there with them. And I'm just not that good. So I won't bother. I have found that I'm 'enough' to attract someone initially, but not 'enough' to sustain their interest long term.
And every time I think it would be nice... something like that happens to remind me of the reality.
