You want them, they want you?
When the timing is right, old loves are allowed to be resurrected. Old loves are allowed to try again.
You don’t have to get over him completely. You only have to accept he is gone, he is never coming back, and you can build a perfectly happy life without him.
Over time, the pain becomes more manageable and begins to dissipate if it’s allowed to be there in the beginning.
You don’t owe anyone a declaration of happiness as a front to how you’re feeling.
