I really need some advice here guys!

So there is this girl I met. She broke up with her bf of 2 years like 4 months ago. He left to school out of the city and cheated on her.

This girl is close friends with my bestfriend's girlfriend. She introduced us. We have gone out like 3 times partying as a group and she was there. We had fun and we also went to Vegas. In Vegas we had a great time I # closed her, kino, and connected with this chick. I would isolate myself and she would follow, so I know she was interested. However, we get back home and I decided to text her and she is a SLOW texter. She takes hours or sometimes she doesn't reply. We have more fun goofing off on facebook if anything. My problem is this I am trying to get her alone to go with me to grab ice cream or something casual so I can connect with her more in person, but that's been my problem.

When I asked her she said for us to go the following day. I texted her the following day and I got no response back. That was last week.

How can I get her to chill with me? I don't want to ask my friend's girlfriend because I want to do this alone. We are going camping in 3 weeks and she is going. Should I just not contact her until we go camping? Should I text her? I want to call her, but she obviously didn't seem interested in texting so idk how she would feel me calling out of left field.

Also, I know she is still a little bummed about her ex but that night in vegas she told me she is finally getting over it and feeling happy.

I hit a road block here and I need some advice.

Thanks Guys

Stop focusing on just one chick, go out and game others.

Gaming others is not an issue. That comes naturally. But this one struck me differently. She isn't as easy as the other chicks I pick up at the bars and clubs and I like that about her. I never have had a challenge until now. And that's is why i am asking for advice.
