Search Results: talking to a woman so hard

Hello.
Known this woman for two years. We are coworkers and always got along fine. Turns out at first she liked me and thought I was attractive. I know this because her friends told me a few months ago and even she admitted to it. Good.
When we first met I never paid attention to her but eventually she changed something about her and stood out. She was attractive and very sweet, I noticed. I confessed to her I liked her and wanted to go out with her. She told me no but we continued meeting at work and still interacted normally. I know she still likes me and all and I'm like then why won't you give me a chance to try? She kept telling me she needs space, that she's busy. I don't want to be clingy, because I'm the complete opposite of that but I like her, she likes me, so what's the hold up? Turns out she's getting to know someone else but never told me. I told her a couple of times I don't get offended, she won't hurt my feeling but I want a NO, not a "I'm busy". I'm guessing she can't bring herself up to being so direct but goddamn I feel so played and manipulated. Like she's considering her options. She's started asking me questions about my work and what I want for the future and I wasn't born yesterday, but just tell me you are closer to someone else than with me. If he doesn't work out then I guess I'm next? I don't know what to do. I feel like I want to play her stupid game and start going out with other women, make her jealous. I know it's so bad and I hate it but it's been a year since I confessed. Really now... I really like her but I feel the impulse of just cutting ties with her. I cannot believe.
Is this normal? Do grown mature women do this? By getting to know him I mean being really touchy with him. She once told me she couldn't say because "I have to consider if a person is good or not". At first I thought she was talking about me and I'm like yeah I'm a good person, I try. Now I see it's the other guy; if he's not good then I'll consider you
