<human>: I've had a massive crush on this guy [28M] for over a year. We've been flirting, e-mailing, etc and it's been fine. I've fantasized about all kinds of scenarios, sexual and otherwise. I've thought about a relationship with him.

So, tonight in an e-mail he asked me to get coffee so we could "talk". It isn't even a date. It's not even a sign that he's into me. It's possible that it's nothing! But, the idea has me panicked. The thought of, I'm not sure, being tied to someone in any way makes me physically ill. Though, in theory, yesterday, that thought didn't upset me.

This has happened before. Lots. I can't explain it very well. I don't know what to do or what's wrong with me. Help?

<bot>: In theory I really like people, I want a relationship, I want it all! In practice, I panic and run away.
