I told her how I feel and got no reply?

Problem is I made two big mistakes, I did it over Facebook whilst she was in work. She was taking ages to reply and as soon as she started typing I wrote "dw, its all gravy" and then logged off. Bad move by my end but I guess I bottled it, not wanting to get turned down. I don't know what to do now. I'm a fool tbh.

We were somewhat seeing each other but not officially and neither of us were to make a proper move. A group of us went clubbing and I was my usual self of pretty much blanking her caues I'm too much of a sap to do anything - she ends up pulling some other guy that was on the bus and then apologizes for it the next day, that's when I felt the need to tell her - now I wish I hadn't.

So what do I do now, contact her and say something or wait for her to give me some feedback?

She initiated conversation with me on Facebook - idle chit chat, asking questions such as how am i, up to much etc. Does that mean anything? Is she dodging what I asked her or does it show she's still interested in talking to me?
