Quote: I stayed very still while she went to sleep and quietly snuck out of the bed to take a bath
Why did you even let her head hit the pillow?! Next time you're in this situation, meet her as she comes out, sweep her into your arms, plant a deep passionate kiss that doesn't even allow her to resist, pick her up and carry her to the bed (if possible, otherwise adapt as necessary), and don't LET her fall asleep!
Everything was primed and you both turned passive at the end. Sure, it'll be great down the road when she too will often take the lead in these circumstances. You aren't there yet. Until you've gotten there, you need to take some initiative at the point in this particular evening when the ball got dropped. (How's that for mixing metaphors?)
I, too, am very sorry that this evening didn't end the way it should of. But neither of you attempted to get anything going.
