Crush invited me on vacation?

I've been crushing on this chick for a while now and we literally spent the last 15 days together studying after school (both in junior college).like 6-8 hours alone time every day. I told her a few weeks ago that I liked her but she said that she wasn't ready for a relationship + we've not been intimate but we flirt all the time. However, she just invited me to go abroad with her (im from cali) and her family. What are these signals all about?

ps. the last time she was on vac with her fam, her (now ex) boyfriend was along with them.

soo confused
