I met this girl,

So I met this girl in my city, she was travelling we met in a bar after some we was kissing and doing things in my car, after that I went to another city she was in my country and slept together for 2 nights, the third she insisted for me to stay and payed for a room.
After that we started chatting I told her I didn't really like chatting but we did it for like 2 months every day for hours, then I went to her country and I was feeling weird, like she was different, she was mean and boring and was treating me bad so I started feeling like ******* weird, I didnt know what to do, I was really emotional, not just for her but for a lot of **** in my mind, sometimes she has seen me cry and we was talking about this thing between us going on even after I came back, and she was saying just: you really want this to go one even after you go away? Like she didn't, but she asked me multiple times to move to her and marry.
In the time I was there I wasn't like in the mood of fun and play but I was really close and thinking about so many things.
After like a week she says she was sorry for treating me mean and wanted to be different, I was confused cause she was saying that, and at the same time she was like I'm not ready for this I have a shield on my heart, if we met in a year from now things would have been different, but saying you make me feel good, I see you like my future husband....like what the **** you mean? Anyway she promised to come visit me in some months but after I came back, two weeks ago, she's not texting like before, she just asked how my flight was and when I text her she says she's busy and we didn't talk since then, she just asked for some pictures I took of her....
Now I have feeling for her, but I'm confused I don't know if she want to keep this on, why she promised to come and now she doesn't text me like before? Why she said she sees me like her future husband but she said she'd not ready?
Should I tell her that sometimes I wanted to ask her to bring me somewhere and leave me there and just say goodbye? Why she's not texting me like before?I have so many questions and I don't know what to do if I should send her a long text trying to explain how I feel or just keep it cool and don't text her too much if she doesn't...
Is it possible that she wanted just me to go there, have some fun for that time and then, nothing?
I don't ******* understand and I feel like I could mess all up if I do something wrong...
Anyway English is not my first language but it was her.
