Okay so there's a girl at my work who I was sat next to for about 3 months, my feelings definitely grew towards her and I feel she does like me back, about a couple of weeks ago they had a move around and she was moved into another team (same department) we are still pretty close but I want to try and progress things. I have messaged her a few times outside of work previously and she will give a good response but she never messages first, eg recently she responded with 'Hey you (winky face)'. I recently messaged her asking if she would like to catch up at some point, she responded and said yes it would be good to catch up and to let her know when im free. I do get some mixed signals, as I said she never messages me first outside of work but we have good talks at work and she does email me. I dont want to seem to pushy but I would also like to find out how she feels about me, what could I do?
