Hello again.
I thought I'd share some of my morning musings with you and gain some knowledge/insight in the process...
While we were away, my boyfriend mentioned the fact I've said to him before that I couldn't tell you the last man who fancied me. I don't think I'm unattractive - I'm nothing special but I'm not the ugliest bug at the ball either. I think I've got a reasonable figure, I dress in a way I'm happy with and I make a reasonable effort with my hair and make up. So whilst I'd never 'turn heads', I must appeal to someone somewhere. My exH said that in a room of 50 random women, I'd be in some men's top 10. Which is about as much as I can hope for! 
Anyway, he thinks one of my male friends has got a 'thing' for me. He's not bothered by it but I think he's a bit bemused by the fact I can't see it. And I really can't! He's even tried explaining why he thinks it, and whilst I follow his line of thinking, I still don't think that this friend 'fancies' me or finds me attractive. But I will accept that he's fond of me in a platonic way, because we're friends.
In fact, I had to ask him a few weeks ago if he fancied me because I wasn't sure. (Idiot that I am!)
Now for a while, I assumed that it was just that I was sending out "fuck off" signals for years, but since my exH moved out, I know I haven't been doing that and I have actively been 'looking' to see if I can see the signs, but I can't!
I mean, I have made fleeting eye contact with a stranger on occasion, but only in a I've been looking around at the same time as them and our line of vision has happened to cross sort of a way.
I never get 'checked out'; I never catch men looking at me; no one ever tries to hold my gaze; I never get approached or chatted up; I've not been asked out by someone since I was a teenager!
So, not that I'm interested or looking now anyway, but how do you know if someone finds you attractive/fancies you?!
