Okay. I'm older

and am part of a long-term relationship. I can't see someone who would be nice enough that you'd become interested in her, saying she was falling in love with you and then walking away. I suspect she may also be wondering how you are feeling. She may even have consulted with a girlfriend who said to play hard-to-get and that's why she wasn't home last night.
I have high hopes that in the past few hours you two have connected. When you do finally connect, tell her how you feel... that you've missed her physical presence and thought about her a lot. Assuming that she continues to make signals that she feels the same, I suggest you make plans for the weekend early so you have something you can count on. It sounds like you may both be very busy and are not as available during the week as you'd like. Having a special date or get-together planned will increase your commitment to each other and help with your intimacy.
Obviously, if she isn't interested in making plans or continuing the budding relationship, then you'll find out quickly. But best of luck that she is also miserable and wishes you were there with her. <Sigh, ahh, young love... so sweet>
