I also agree that , sometimes when a love ends, you feel like, how could this be, i thought we would be together forever. And then like i duno a year later you meet someone who you feel more strongly for than anything in your life.
I do believe that certain things kinda happen for a reason. I believe for the most part, especially if you are putting Jehovah first, and rely solely on him, that he won't let you "end up" with someone who you shouldn't be with.
