I married my best friend

My bestfriend when I was still a kid we were so close that she even knew about my life. I didn't have much friends but I love talking to her and spending time with her. We became closer before we graduated high school so I ask her we can keep contact. College was hard and she became my gf and I proposed to her a few months after college and she said yes! Thinking about our past makes me happy about my decicions and when we had sex she told me shes a virgin and she was so tight. There was a time we were so distant we only talked when we had to.. And thinking she my bestfriend and have a huge crush on her when I was akward 1st grader and I love her.. Do other people also marry their bestfriend?
