Yeah, so I got refused a k-close after a really fun evening with this wonderful line:
"Friends last longer."
Ouch!! Not in this case, sweetheart

Thing is, it's a good enough excuse to move on from this girl, as she was rather dull company overall, and I persisted because it was the only option available at the time.
There were many things I probably did wrong by PUA standards - didn't take the lead often enough, waited too long to make a move, didn't escalate properly - but my main issue is how to behave now I've decided to finish chasing this woman. I know her through friends of friends, so it's not impossible I might bump into her again somewhere.
I think she still believes we can be regular friends, and will likely contact me to go and do other stuff, so what should I do in that case? Ignore her altogether, engage with her, or just fob her off with excuses until she gets the message?
Also, what if she realises, and asks me whether I've stopped talking to her because she shut me down? Really could do with some guidance, people...
