There is this girl I work with who I like and we went out about four times two initiated by me and two by her. The last one we had dinner in which I suggested that we eat at a certain place but when she confirmed she wanted to go somewhere else in which I agreed because I had never been, and plus I thought it would be a good experience, also she was late because she wanted to take a short nap after her work. Since I always tease her and call her by a pet name and I bought a small cheap toy related to it, and some candy in which I gave to her during dinner. Now during dinner I didn’t notice any indications of disinterest and we had a lively chat. After dinner we went home but no kiss or anything but I did during the evening make small physical contact in touching. 30 minutes after arriving home she texts me and said that she was flattered that I was attracted to her but she sees me as a coworker. I responded to her the next day and said that I was seeing someone else and we could be friends. We work at the same place but in different offices, and her apartment is one floor below mine. I have moved on and am seeing other girls but a few times she has initiated contact after I had went into NC which is difficult to do because of working together and living locale. We have texted but not very often maybe three times in the past few weeks and they have always been short. Also during the NC she always seem to run into me yet I was trying to avoid her, and she has given me a small gift as well. What can I do to turn things around or am I doomed to the friendzone forever?
