Should I have stayed? Think this was a MASSIVE faux pas

You can skip 2 paragraphs to the important bit...

Went to see a mate who was working at an archaeological dig. As usual, when I got there met everyone, and kinda thought "hot, hot, not, she's nice, they're fit too" the usual. Then decided, her and her are hot.

I was there for 5 days ish, and on the last night, I ended up kinda sleeping with miss marvel. The one I'd liked right from day one. I didn't come onto her, we were at the disco, and she came up, sat right next to me, legs touching mine. I read the signals, kissed her, and she invited me to her tent. There was more chatting that I detail, but yeah. We chatted afterwards, "post sex talk" about uni and rest of it. Anyway...

IMPORTANT BIT >>

Woke up in the morning now, said morning and all that, and I got up to go toilet, I was fully rested for the day, but she looked like she wanted to sleep, and I'm a fidgeter, and id already woken her up twice, because she was laying like on my chest and I can't keep still.

Me: shall I come back in, or should I let you get some sleep? because I know my fidgeting is bothering u

Her: Up to you...

i know that is a MINEFIELD "up2u"

what should I have done ladies? I really like her, and I'm thinking iv made a mistake.

Also, if I did, what can I do to fix this?
