Not putting any effort into contacting me. She and I would talk constantly when we saw each other and we both got on very well with each other. She, however, was practically a workaholic (though, I don't blame her in this economy). Three jobs plus college full-time, the third job was just seasonal for Christmas and that's really the only time we'd talk.

After we exchanged numbers, she really would only text me back when she felt like it as opposed to when she had time. She eventually asked me out (I was holding off until I felt she had time). She wound up standing me up. Managed to get a hold of her the next day, she said she decided to go to the gym before the date and meant to only take a 15-minute nap but wound up going 3 hours. I figured I'd give her another chance since she went out of her way to apologize in-person and because what happened seemed understandable given how she overworks herself. It was then impossible to get a hold of her for a couple weeks (not even a 5-second text saying "sorry, been busy; we'll talk as soon as my load dies down, ok?"). I moved on and when she heard I was showing interest in a mutual friend, that's when she decides to make time to text me... To criticize me for not waiting for her.

I'd probably give her another shot if she's able to actually have a dating life now but back then? There's a difference between being busy and being actively unavailable.
