We go to the same society but I've been going for a couple of years and she has just started. She always comes to the socials and for drinks when we go out. I am the person she comes up to all the time and talks to. There was a drinking social on Monday and she was sat next to me quite close. She spoke to me more than everyone else and when I changed seats she asked if I'd rather sit next to her instead so I did. She was sitting very close and seemed to be being flirty, always going to the bar when I did and when we went to a different bar she made sure she sat next to me. Then it turns out she lives quite close to me so when she was leaving she asked if I was going aswell so I could walk back with her but I was staying out so I didn't walk with her. Do you think I am looking into this too much and do you think something could have happened if I walked back with her? Also what advice would you give about the situation?
