A year ago, I had feelings for this girl and asked her out on a date. She said she’ll think about it. Then a couple days later, she tweets about going out with me (without mentioning my name) but doesn’t tell me directly. So I text her and she confirms we’re going out. About a week after the date, I ask her on a second date and she says no, she has feelings for another guy. I didn’t reply.
Now, a year later, I’m moving away to another city that’s about 1300 miles away. I start telling people that I’m leaving and I’ve been on the fence about telling her, especially since I haven’t seen her in a year. Then I find out she tweets that she hates it when people leave and don’t say goodbye. You never know when will be the last time you’ll see someone.
Why would someone invest more time into talking about you online than to you directly? If she feels that concerned about me leaving, then why doesn’t she just text/call me?
She sounds awful honestly, most likely she is a really passive aggressive person, waiting for the others to feel guilty for her. Imagine in a relationship, when any problem arises, she would never have the courage to face any conversation directly but will wait to be investigated and to trigger guilt in someone before anything gets sorted out, and getting even more angry if this procedure is not followed. On top of that, since the person who should read it is not explicitly specified, she has the power to decide if she likes the reaction or not, either discussing it if brought up the way she wants, or denying it was targeted at them if she is not satisfied or too exposed.
That is so damn pathetic it made me cringe physically, contracting my mouth when I read it. If I knew for sure the tweet was directed at me I wouldn't even contact her. Or I would, but telling her that this is not appreciated at all and to fly down with her bullshit. But since you are leaving you don't want to create enemies right now I guess, so I think you could just ignore her or meet her very briefly while meeting other people, something not too "dedicated" perhaps.
Lastly, you don't owe her anything, she was a casual date who rejected you for another guy and even told you that in a pathetic and disrespectful way through Twitter, so you have all the rights to not dedicate her any of your time. Rather, if anything, she should reach out saying something, like:"I got to know you are leaving, is that true?" and not expecting you reach her out. If anything.
