I think this girl from work wanted me to make a move. I didn't, should I now?

She took me to her house after a long nice dinner and conversation. She took me to her bedroom but we just talked for a while and I left. She's been a bit odd on some days towards me, on other days as lovely as she usually is and more since that day, just depends on the day. We haven't really brought up that day and it's been a few weeks. I think I should make a move whenever she's not being odd and barely looking at me. We usually walk to the station together after work, might that be a good idea to invite her to eat something together?
