Would you care to accept?

Out of nowhere got a follow request from ex— about three years ago. Back then, loved her deeply, but she was the one who initiated the breakup, and got no take on it. Just go with flow kinda thing. Now, I, obviously moved on with life, healed from whatever that was, and grown as a person.

What would you do in this situation? Would you accept the request out of curiosity, nostalgia??? Or would you decline it, as chapters are better left closed??
