Sometimes things are just not meant to be. Sometimes the only way you can move on from someone is to realize that you gave it your all and that you loved them completely empty. I think that when relationships end, the best thing that you can do for yourself is to, learn from what it is you did wrong and build on what it is you did right. Sometimes you may never know the true reason why it ended. Every question you have is not meant to be answered, and every person you love is not meant to stick around forever. Live your life in a manner that will always have you moving forward no matter what happens to you. Relationships that aren't meant to be, always have expiration dates. Your "ending" is also your "new beginning" to do things differently and in a better way the next time love decides to come around again. And when it does, try your best loving that new person like you have never been hurt before.
