Hey girls (or guys) can you please help me with this?

I have been seeing this girl for about three weeks now. She has bombarded me with text messages and phone calls. She called me all the time. Asked me to do stuff with her non-stop. I did see her a lot this week. I would say one or two hours each day for six days. But I had time on my hands and wanted to get to know her better. It was never me asking, I was just agreeing to her asking me out. So today, I get the "I think we should slow things down, I need my space." talk. She told me that it wasn't me, it was her and that I was acting like I was too comfortable or something around her. I think she was referring to maybe public affection? We have been making out a lot but once again, she was starting them just as much as I was. She keeps saying she wants space, so I'm going to give it to her. I deleted her number. My last words were "I don't quite understand or know what happened today but if you want to hang out or something just give me a call. Take care". Then I deleted her number. Just 12 hours ago she was asking me why I didn't go to a party with her friends since all her friends had a boyfriend there with them. 18 hours ago we were making out. I never referenced her or acted like she was my gf. I have no idea what transpired today. So what do I do? Is this one gone? I guess I should have rejected her wanting to hang out? I am disappointed and all since I liked her, but the only choice I have is I guess to move on. Can I recover from this? Or is this one gone?
