Your story is reminds me of that saying "If you love something, let it go. If it comes back, it's yours; if it doesn't, it never was." I think unrequited love is something everyone experiences. I'm sorry you've experienced it, but you have to remain focused on the positives. The other saying that comes to mind is "It is better to have loved and lost than to have never loved."
The thing that got me through mine is "if it was meant to be, it will always be." I hope one day you may come to realize that the experience will make you stronger and a better potential partner. It may not seem like it, but it will in the long run. Stay strong and true to your heart!
