When people are young, they’re still developing and changing, trying to figure out who they are. At this age, you’re basically trying to get your adult identity and figure out where you fit in this world. Meeting at such a young age, it’s rare that it works out due to these reasons. She probably doesn’t want to feel “tied down” when she’s still young and exploring herself too. It’s common to date around when young, but doesn’t make it suck any less when your heart gets broken. Relationships take commitment and effort. Not everyone is on board for that stuff, or ready to take on that responsibility at a young age. Sorry dude, smoke one and take some time to think. I’d be willing to bet that if you asked her why she did it, she’d say “i dunno“.
