So,
I've been chatting online & txting this girl for a couple of days, we were getting along ok, flirting etc (even showed interest in coming on a mini-trip with some of my friends of mine that was being planned).
Anyhow she suddenly stops replying to my messages and made no contact with me for like 2 days (I know that she wasnt away or anything).
So I stop trying to contact her after like two ignored messages. And 2 more days go by..
Then I get a text from her, "Is this trip still going ahead?

"
HERE is where I need some pro help

Should I be cool with her, act like nothins happened? I'm really unsure.
MUCH APPRECIATED.
