So I had a situation about 2 months ago where I was obsessed with this one chick and things went something like this:

1. Ask her out first time, she flakes.
2. Ask her out a second time. She preemptively flakes (or shit tests?) by telling me that she has something super important to do the next day and if we can schedule for a later hour. I tell her ok, "find out when that thing is so I can make my schedule". I don't get a reply until she tries to call me the next day an hour before the set date. I'm angry enough to not answer her call and send her a text "I'm busy. Ttyl". While it was hard enough to do with a girl I've oneitis for, apparently this kind of behavior is exactly what works.
3. See her about 10 days later at work and she goes up to me with "whyyyyyyyyyyyyyyyy did you flake me?" in front of everyone there. I tell her I was busy and if she really wants to see me, it's up to her to set up a date.
4. I get a call about 2 days later and she calls to ask me out for a cigarette. It's 10:00 PM and I live rather far from the city so I say "no.".
5. 2 days pass and I decide to try for one last time. Call her and tell that I'll be riding bike tomorrow and if she wants, she can join me. She says yes. She doesn't turn up, no phonecall nor text.
6. 3 days later like clockwork I receive a text with a long bullshit reason and a bait at the end "but what about X days from now, are you free?". My reply was "lol". I was fed up. I cut all contact with her from that point.

Fast forward 2 months later, I'm trying to focus on my work and myself and I have to reopen my FB account for work. She somehow finds me and adds me. First thing she posts on my wall is a "♥" emoticon. Now obviously there is nothing I can say to this other than reply with a joke. She continues to stalk/like my shit. I strike up a convo with her and tell her that I'd like to see her when I'm in town. She replies with something to the effect of "when the hell is that going to be?". I tell her that it's probably not a best idea to do so if she's going to have that attitude. "Lol. But come on, tell me when you're coming back.". "Should be back in a day or so.". And that's it, nothing more.

Tell me men, am I just torturing myself here or do I actually have a chance? The only thing I'm interested now is a revenge fuck, but I really don't want to set up a date just to get flaked again. Gauging from her response, she doesn't seem that interested. Advise me bros.
