Input: Last year, this woman (26 F and me (25 M) hit it off. We got each other's rather cynical sense of humor and I thought she was just raw awesome at the time. I didn't even realize I had fallen for her until the fifth time I found myself fantasizing about her. (In my defense, I was incredibly sheltered by my family who either were really extreme Catholics or used it as an excuse - I didn't even have a kiss until I was 22 and no one really bothered to explain the birds and bees to me. Had to learn everything myself.)

Well, she had given up on relationships and was not looking for anything serious at the time we were hanging out.

I copped on, thinking "you can still be friends, you're an adult" meanwhile still pining for her like an idiot and not even knowing. Kept trying to be happy with the decreasing time I spent with her as she found other people to hang out with.

Finally, I ghosted her after sending a message where I admitted it to her and told I was sorry for not being able to get over it. Deleted all my social media and about three months in started dating. That is literally the only thing that has changed: I'm still at the same job, same glasses and same damn haircut.

Two weeks ago I finally got back online. She then tried to reach out to me on my new social media page and wondered where'd I had been.

Told her about my life to be polite and she got weird about me mentioning the fact I had been dating in the time since we last talked.

After a few turns of "I never thought you'd be like that" and her trying to steer me into flirting like when we first met and brought up when she had a crush on me, I got fed up and said:

"Why are you so concerned about my romantic life all of a sudden? I was willing to do anything for you once, and that wasn't good enough to even bother to call me. I tried to respect your beliefs even as my unconscious mind fought against me. You had a chance to be my friend, but you didn't want to be that either. If we're going to play this shit again, please just block me now."

Blocked her, then she posts the conversation on her wall and now everyone is tearing into me for getting so hostile with her just trying to be friendly.

I don't think I'm wrong but given the absolute volume of responses I got from other people, I'm not sure I'm reading the situation right. AITA?
