So, at work there's this girl who I've been getting along with - jokes, flirty glances, easy conversation, etc. Then last week she voluntarily gives me her phone number on a post-it note with an x underneath. We exchange a few messages outside of work - everything is good so far. Yesterday I decided to ask her to go for a drink after work, she looks at me with a puzzled look, laughs and says, very definitely, no. She's been avoiding me since.
I'm no expert on the fairer sex but that's just odd, right?
