It's not in the case of love, it's in the case of everything.
Nothing lasts forever.
Nothing ever will.
Someday it's gonna go away from you.
But it doesn't matter if they aren't there anymore or that thing ain't there, what matters is the moments you spend together, the happy moments, the sad moments, the battles you fought together, the time you cherished.
You can only cherish the moments you spend together because that's gonna stay with you.
What matters is who stayed with you and for how long and who gave you the happiest memories.
It ofcourse hurts when someone goes away, but everyone's gonna go, we can feel blessed to have spend those moments with them if they did you right <3.
And ofc it's not the people who did you wrong and who gave you more hurt and almost a bit of happiness. That's gonna pass away, the hurt gonna pass away.
As said nothing stays in your life, no feelings, no person, NOTHING.
That's how we make peace with that.
