Is it normal to think this way about something?

This is a bit of a long story, so bear with me. Since I was 15, there has always been this one girl that I could never forget about. When we first came across eachother there was definitely something between us but I was too hesitant to make any more* advancements. (Something I've came to really regret) She seemed very different than other girls....very fiery, but at the same time very understanding and calm about things. By far one of the most beautiful girls I've ever seen, too. We were similiar, yet very different. I've told her things I would never tell anyone, and she just listened without judging. She's agreed with me on things that many other people just didn't understand. I've told her how I've felt, and she never pushed me away until recently. (She's been off and on with someone and that's why she finally did push me away.) There's been quite a few strange situations that have happened over time that really got me thinking about her and the situation as a whole. For instance, I've seen her once or twice a year since we stopped going to the same school (my junior year, her sophomore)and each time I have seen her it's been perfect* timing. I'm not a weirdo, I know how to think about situations logically and I don't usually think about things too deeply. It's just tripped me out how everything has played out to regarding this.. What is your opinion on "fate"? Or the saying "all things happen for a reason" & the saying "If it's meant to be, it will happen". What's your opinion on this situation?
