Should i have made a move or have i blown my chance?

So i've been talking to this girl for a couple weeks and have hungout a few times. Usually for the most part im pretty relaxed around a girl but when i hang with her i always get nervous! Anyways one night we had people over at our place and she ended up staying the night with me, however, nothing happened. Not that i didn't wanna make a move but i didn't know how she would react if groped her the first chance i got. I feel like at the time it was better to wait and take things slow but i'm scared i might have blown my chance now! she still flirts with me and we text pretty often but she's yet to stay with me again. Did i blow my shot??? or is it best to keep things as they are and just see how it plays out?
