Contrary

Me and my SO have been together for the last 2 years of my highschool career, graduated a week ago both at the same time, and the day after, she breaks up with me, saying that we've been together for so long, and that she needs to get out there and see what the world has to offer, but that she cares about me a lot still, and that it may not be completely over for us, but she wants to be single for who knows how long. I still care for her a lot and im having trouble getting over her, but i just wanted to know if this is typical for people to do after graduating highschool, and maybe what i could expect from her down the road.
