Is She Hinting For Me To Ask Her..Or Is She Playing Games? Long, Interesting Story?

I've been talking to a girl for about a month and a half now. We met online and spoke for a few weeks and finally went on our first date. We had a lot of fun and she seemed shocked by my gentleman like demeanor. We went on our second date had a blast and I built the courage to kiss her. She liked it a lot. We still continued to talk and date. By our fourth date I asked her if she was ready to be my girlfriend. She said she needed more time. A couple of weeks ago I bought her a rose and she was stunned by it and thanked me with a hug and a kiss. A week ago I bought her a card. It was corny but she smiled and liked it. She stated that it was the first time a guy has ever gave her a card without any special occasions. We further continued speaking and dating. We kiss each other good night when we go out and I text or call her to say goodnight every night. A few weeks ped and she still hadn't mentioned if she was ready. a few nights ago I asked her to be my girlfriend. She said, "Just give me one more time." I umed she meant one more date. She mentioned that she was going back to school in the fall and I ume she's worried about that. A few nights ago she came over to watch a movie with me. We made out for a few minutes after the movie and I told her that I couldn't get enough of her. We consumed some alcohol, but nothing excessive. She eventually left and she sent me a text when she arrived home saying, "All's good ;)". Before I could respond she sent another message stating, "If you can't get enough of me, why don't you do something about it :p?'. I told her that I thought she needed more time. She fired back with, "Well I didn't say that exactly..lol.. I'm gonna shut it! Nite." I immediately grabbed my keys and told her I was coming over. I sat in her driveway and she never came out or responded because she fell asleep. She sent me a text the next morning asking me what I meant. I told her I came over to ask her. She laughed and said she was, "just messing". I was so confused at that point. Two days have ped and I haven't brought it up. We're going out tonight and she seems very excited about it. She keeps hinting on other date ideas. Was she telling me in a sarcastic way that she wants me to ask her.. or was she just jerking my chain? Ladies and gents..I need your advice and words of wisdom.
