What do I do after she friendzoned me?

I've went on 3 dates with a girl I met from online dating and they've all went really well. We've found several things in common and had lots of laughs, but at the end of the last date she said she thinks of us as just friends. When she told me that I just said something like "ok, thanks for your time" and then we parted. It's only been 2 weeks since we met, I'm just thinking we may need more time. Should i keep in contact with her and stay friends or should I just let it be? We really have had good times together. Could I ask if if she still wants to hang out?
