Could I turn this fellow co-worker into a relationship?

Ok I got this co-worker who at one time I actually spoke to for 3 hours straight at work. We usually talk everyday for 4 months but we never talk outside of work or hung out outside of work. She seems very shy in doing anything thing outside of work. We have so much in common and even fellow coworkers notice we have a thing for each other. She even made me a stick of butter from scratch and brought me lunch she made herself. She only did it for me. So we had a weight loss bet of who would lose the most weight in 6 months they would get $500. I found out from other co-workers that when we started talking she just got out of an 7 year relationship so maybe that why she was reluctant in doing anything outside of work. 2 months in the competition she kinda gave up knowing she will lose but she told me she will go through the whole 6 months with me. She told me that before she made the bet she knew she was going to lose. I told her why she went through it. She told me that when I lose the weight I would get a girlfriend and look good for the next girl but not her. I’m confused as why would a girl want me to look good for another girl and give away $500 or do you think she is pulling my leg and deep down she does like me and she needs time to recover from a 7 yr. Relationship and don’t want me to push being in a relationship with her for the time being?
