best way to act around female after she rejects you

[kabobra]

So I had a girl from work throw a lot of signs at me a while ago. I didn't have feelings for her at the time. Now I do
have strong feelings for her and wheni asked her out she said that she has been seeing someone for almost a month. I am going to continue pursuing other girls but I'm curious what are some things she might notice concerning the way I act around her now. I went back into work after we had the talk and I stayed positive, showed that I wasn't upset (but I really am). Pretty much tried to show that I'm moving on and I was still kind to her, didn't ignore her or act weird. She was the one that actually acted awkward and I kept moving on like nothing had happened. What are some things that I should make sure I do just in case that new bf doesn't pan out and I can stay on her list?

what you're doing is good. act like it doesn't bother you (even though it does), and just continue to be nice (but not too much), act like you said you are, like you've moved on. don't be horrible to her, her show any jealousy or anything like that around her, because you might blow your chances completely. i think what you're doing now i fine... good luck!
