<human>: Do about 2 months ago I met a girl on my flight home. We hit it off immediately and ended up spending every day of her vacation together. She even extended her vacation by a week (to 3 weeks) to be with me and the whole time was amazing. This was the strongest connection I'd ever had with a girl. 

Unfortunately she then left the USA to return home. We talked about it and decided we would stay in touch and try to see each other in the future, because there was obviously some very good chemistry between us.

That leads us to the present. She has now been gone almost a month and I am totally confused.

We talk pretty frequently and she says that she is really into me and would like to go skiing with me in March and then spend the summer together. But there are all these little signs that kind of bother me:

1. She wanted me to come see her but when I got the money to buy a ticket she came up with a bunch of reasons why I shouldn't and said we should just meet in March to go skiing instead.
2. She rarely texts me unless I text her
3. She hasn't called me in about 6 days. The only time I get to talk to her is when I call her, and usually she does not pick up.
4. She normally says she needs to sleep or go do something after we talk for like 15 minutes.
5. She says she is really busy and stressed at the moment with work and doesn't have much time to talk, but she goes out and does things with her friends all the time.
6. She changed her Facebook picture today from a picture of us to a selfie she took in her room

That's about it. Please help me Reddit! Tell me whether I'm crazy or not and help me decide what to do next. I really like this girl, but there seems to be something going on. Thanks!

Can you condense the text into three sentences or less?
<bot>: Had amazing chemistry with girl on plane. Now that she's back in her own country I'm getting mixed messages about whether she wants to see me again. Can't decide what to do.
