<human>: Give me a shortened version of the text

So I've been seeing this girl almost a week now, we clicked straight away and really enjoy each others company. On the days we haven't hung out, we've played LoL online together and are constantly txting. We've both admitted that we like each other and are keen to move things along.

The problem is, I've just gotten out of a 2 year relationship, and I struggle with crippling anxiety. So I'm rusty on the whole dating thing and constantly worrying about messing things up with her. So far so good though.

She came around for dinner 2 nights ago, was awesome, had dinner, watched a movie and half way through the movie, I finally made a move for her hand which she gave me, then another hour I put my arm around her. Then when I walked her to her car, I gave her a kiss (just a peck). She txted me later saying she had fun, I asked her if she wanted to hang out again Thursday (today), and she said yes, and suggested we get dinner and go back to her place for a spa...

So it's now Thursday, and I'm a little nervous about tonight. Seeing as though we've only exchanged an awkward kiss, am I to expect that she is wanting to go all the way tonight? I'm so rusty that I'm clueless and feel like a pussy for not making moves sooner haha. Also, I've never shared a spa with a female... How does one make advancements in such a scenario?

Also not sure on how to do the whole changing into swimwear thing either... Should I just change in front of her, go in underwear? Really really want this to go well but don't want to make her uncomfortable.
