Getting Out Of The Talking Phase

I've been thinking about this a lot lately. I've been single for a while now, and getting back into dating has been terrifying, fun, horrific, you name it, I've felt it.

But what happens when you like someone and *gasp* they like you back? How do you... start dating and get out of the weird talking, situationship phase? Because suddenly you have what you wanted and now someone is wanting to see you, wanting to make plans, and it's overwhelming.
