That really depends on what you did. I know that when I am really angry about something, I often prefer to just not say anything at all anymore. And the last thing on my mind at that point is manipulating someone else. Also, it's never a good thing to assume your gf to be manipulative. You have to assume your gf is a grown up who wants to cooperate with you. Of course you should also be realistic and if she's manipulative, it's better to go your seperate ways. But if you're already paranoid about it now, I don't think that's a healthy attitude.
I got pissed off over something stupid when I was drunk and left the party she invited me to.

Tell her you weren't interested to begin with. She'll come back crawling.
