Did I blow it?

Alright, so a friend of mine and her boyfriend set me up with this girl I really like. It was like a double date. We got along really well and we had a lot in common. I could tell she was having fun, and we made plans (as a group) to hang out again. But since I really liked her, I got her number from my friend and I thought I'd ask her out before that. I made the mistake of texting her instead of calling. I asked her if she wanted to hangout, and I didn't get a reply. So I don't know what to make of it. At least if I called her I would know either way. So does the fact that she didn't reply mean that she doesn't want to go out with me. Did I completely blow it? Help me.
