Need help with girl problems!?

Don't wait until tomorrow. Text her and tell her that you're sorry about acting weird today. She'll most likely be the one ignoring you tomorrow if she was upset today. Maybe call her and explain, but don't wait. You said these mind games screwed up things with another girl, but don't let it happen again. I know it's a lot harder than it sounds, but if you tell her today, at least she'll know. If it ends in a fight, then I'm telling you now mate, she probably doesn't like you enough for you to be making an effort.
