Around 6 months back I approached a girl in my office in the cafeteria. (we don't work together)
I have talked to her a few times but things seem to be getting nowhere.
She sometimes shows some very strong IOIs example:
* Smiles when she sees me (but only when not many people are around)
* Circles me when she sees me with a different girl
* I have seen her friends and her giggling when I come
* Once she was with a guy sitting far away from me and saw me. She then actually came and sat a few seats next to me with that guy (that was weird) . I did not gave her the attention though.
* Although she knows me by now but sometimes totally ignores me even if I am standing just few inches next to few and sometimes she herself comes to me to say hi (but does not wait to talk)
* earlier she used to reply to me on office communicator but now does not reply
* Whenever I do meet her she always seems to be in a hurry to leave
* once I was about to number close but she suddenly disappeared
* she was in an elevator and then I came, couldn't talk as there were people between us. We had to go to the same floor when the floor came she did not come out ( this has happen 3-4 times)
What should I do?
