Grappling with the idea that if they never come back they never truly loved you.

What do you guys think about this? I can see both sides of it. But really I think if you truly love someone you would go back no matter what eventually. And if the other person never takes you back, or never comes back, and moves on for good then they never truly loved you.

Idk, I can see the arguments against it as well. What do you guys think?
