Hi OP, I haven't read through the whole thread but realise you've given him the brush-off, which is a pity. I'm pushing 50 and have dated hundreds of men, having been single my entire life.
I have ended up falling for guys in the past who I had no interest in whatsoever to begin with, and felt no initial chemistry with; they just grew on me over time.
I also have a friend who dated three guys at the same time. She was not interested (at first) in Guy No2, but obsessed with guy No1, a rich executive. Over time she fell for Guy no2 and they are now happily married with two children.
Women can be won around by charm, wit, intelligence and personality; men, on the other hand, know straight away whether they are into a woman or not, because they are more visually driven than we are. If they are not physically attracted to you from the off, it ain't gonna happen. They are different to us.
Secondly, I am a great believer in multi-dating: if you're single, why be in a hurry to home in on one guy? Never be too hasty in casting aside admirers! Why not just enjoy them?
Have fun, get out there and flirt!
