Did she reject me because I didn't ask her out?

I've had a new girl at work that was very talkative and very flirty, touchy and stuff like that for about a month and a half , i didn't ask her out because i was seeing someone else and now this girl has gone very cold, Barely talkative and no more touching or flirting and i ended up asking her out and she told me she's not interested and was only being friendly but stopped talking , flirting and touching out of the blue completely.

Would you guys think that she moved on and got mad at me because i basically rejected her advance by not making a move?
