So not to go into too much detail, but was rocking of confidence for months and had a few admirers which was great. One girl from work in particular was a huge fan but I always kept things professional even though she made very obvious advances. I knew she wanted a relationship but I didn't that's why I didn't reciprocate on the advances. But In the end she wore me down and we hooked up a few times. After a while I could feel myself falling for her no matter what I tried, when I show some interest in being open to a relationship she now has no interest. I feel like I got played on this one, problem is we work together so I can't be a total a$$hole to her, but she has taken my power and I want it back.

How do I get back in control?
