I may be wrong/naive, but I really do think its a myth that men pursue and then when they get sex they reject you. The old conquest/notch on bedpost idea. It makes not sense to me why they would do that, so I don't think it exists. If people have a good connection, chemistry and the sex is great why wouldn't they want to do it again? If something is good you want to keep doing it - not one and done. I have never understood this concept and really do believe its a myth - maybe something we tell ourselves to make ourselves feel better perhaps?
Im a strong believer in pheromones - I know not everyone does. But for me it doesn't matter how gorgeous and scintillating a man is, if the phermones dont do it for me its just not gonna happen.
That said, i still think this man was spectacularly rude to turn his back on you and not give you eye contact - and then to reduce contact by short messages was just weird. If I wasn't feeling it (and Ive been in that awkward position many times in the last 8 years) Im totally kind and polite (but not overly gushy), and then make my excuses later. Very clear, but kind, and I don't do the gradual fade. Sounds like he still wanted the ego boost of you dangling. Which is embarrassing for him.
