Sad to say, some good things, never lasts. . .
You may go far away. . . even move to another planet.
BUT, that can't erase the fact that you're through, not even ease the pain of breaking up.
Yes, it's hard to pick-up the broken pieces but, that's how it ended.
There's no sense in crying over spilled milk. What's done is done... What's gone is gone.
What you could do however is to move-on from there. Learn from it. Life is a journey which ends only when our life is through. . . don't waste time. Life goes on. . . even without him.

As God promised, I may close the door, but I make sure to open a window

Trust in God and I know, someone far better will come your way.
Have a great night.
