Afterwards she didn't seem that receptive, so I left it and pretty much went No Contact and chalked it up to a rejection. Anyway 2 weeks later she randomly emails me at work and sparks up a conversation, saying that she forgot my last name and had to ask around, we chat again and she invites me out for some drinks that night with her and her friends. I already had plans so declined but proposed a night during the week to catch up, she agrees.
Chatted again the other day via messenger, mid conversation I bring up the catching up for drinks. She flat out ignores the question and keeps chatting as if I never asked :S... I asked another question to spare the awkwardness and then radio silence. I don't really understand this type of behaviour, if you weren't interested why try to reengage conversation again and invite me out?
