I am for an exchange in Brazil and i've met a beautifull girl using tinder, she was really eager to meat me we have been sending voice messages etc for quite some time. Last week in the weekend i went on a road trip with some friends and we visited the city she was living. So she invited me to go to a hughe festival with her, i agreed we met in her house together with her friends. We seemed to have a click, on the festival we kissed and at some point there was an uber arranged for me to transport me away lol :) don't know why maybe i was a little drunk. So, she sends me messages that she really likes me and that i am cool. The next day, i asked her to go for a drink. She agreed, we went to a coffee place and talked a bit but i noticed a shift in her vibe. But we kissed again, we moved to another place and talked and kissed again. Now i am back in my city, i still send her some time a message but i have the feeling she's just being polite to respond. I don't know why she suddenly doesn't invest in me, maybe due to the fact that i will be leaving in 6 months.... What could have caused this and can i still restore it because i really like her a lot!
