What then? in General feelings on things

I heard a song today that made me wonder what will happen then?
We’ve been apart for so long, but never gone from each others lives. Not really. We get small moments to share knowing looks. We still get to check in. Occsassionally, we even get the chance to make each other smile again, the way we used to.
Things are changing now. I won’t be here much longer. What then? When I’m fully removed from you, when I become someone you used to know, when you’ve forgotten the way our looks were tinged with sparks of yesterday. Will this finally end? Will we finally give up? Will we finally stop torturing ourselves over yesterday? Will we finally accept we will never feel the same again? After years of walking around with these unfillable holes inside ourselves and trying to pretend they don’t exist, by attempting to fill them with people we know we aren’t meant to be with, will we finally become whole? Will the pain finally vanish. If so, what then? Will we even know what to do without even the painful reminders to hold onto? What then?
