Long story short, there's someone that I liked and at least at some points in time it was obvious that we had some mutual interest. She has been dating someone else and living with him for a while now under questionable circumstances...basically he's wealthy and owns a house whom she was renting from him right after college graduation then they started to date each other after she became financially reliant on him. Personally I think the situation is kind of bad so I've been trying to get her out of it by giving her job referrals and such, and she seemed appreciative of it at least in the beginning. But after a year or so things doesn't seemed to have progressed much so I'm ready to call it quits and move on.
But she did something odd recently that I can't really put my head around...Basically this whole time she was seeing the guy she made virtually no mention of him anywhere, even on facebook, even as I was throwing hints of interest at her prior to that. But recently I casually mentioned that I was going to join the dating scene again and her profile picture suddenly changed to one between her and the guy. Why now, is the thing, since the fact that they've been going out together was already known for a long time? Can I just assume it's a "hands-off" gesture and get on with my life, or is there anything else going on?
Unfortunately I need to be careful about how I talk to her from now on because we work with each other fairly closely on a professional level and no-contact is not a possibility. I still have feelings for her but I understand that the best thing to do right now is probably to distance myself from this as much as possible without hurting our professional relationship. Am I doing the right thing? Any advice on how to go about it?
