I'm a newcomer to seddit, but I've been lurking on here for awhile.

I asked a girl out for drinks last week after meeting her a few months ago and hanging out with her a few times with friends. It's the first time I've proper asked a girl out, so I'm a bit new to this even though I've had girlfriends in the past. I like this girl a lot, but I over-analyze like a motherfucker and I know I need to focus.

Any cues or suggestions? I'm going to be confident over the phone/texting, but my main problem will probably be not acting like an awkward idiot during the date. Help would be appreciated.
