Search Results: adding friend on facebook

Well this girl at the gym tried a bit too hard to hit on me by doing a lot of stretches in front of me (for at least 5 -10 mins) and then making it look like an accident when she came in my way at the exact time i got off my bench to adjust it, and we exchanged a smile when i said sorry and all she did was show how happy she got by just smiling at me and not saying anything. i didn't talk to her was not sure if she was really interested and then her friend told me later that she was into me and trying to hit on me. Then few days after she was doing a workout a little distance from me but seemed to have a stressed out, annoyed/angry impression on her face. So I thought she didn't want to talk to anyone and that's why I just avoided looking at her to give her space. But then she took that personally (as her friend told me) and started avoiding me (looking away whenever we made eye contact). She's been doing this ever since. Freaks out whenever we make eye contact and hurriedly turns her head away. So then I came across her Facebook profile as this friend of hers is a mutual friend in addition to another and she came up as a friends suggestion too. So I added her. But then she not only declined also blocked me from further requests (I had already requested her before that like more than a year ago). I don't want to make her uncomfortable or upset anymore now. So when I run into her in the gym should I just ignore her completely?
