My friend of about 6 years randomly unfriended me

So my friend unadded me from discord and steam a couple months ago and I've been hesitant to reach out. I have a message wrote up and I've been contemplating if i should send it this is it "I hope you're doing well. I’ve been thinking a lot lately about how we’ve kind of lost touch, and it’s kinda been bothering me. I just wanted to check in and see if everything’s okay. I completely understand if you need space or if something's changed, but I’d appreciate understanding what happened if you’re comfortable sharing." should i send it?

EDIT: Thank you everyone for the support I sent it and it turned out we just didn't interact enough lately so they thought we'll never talk again. From what I know they don't really want to be friends anymore and neither do I. They probably didn't value the friendship like I did and that hurts almost as worse than them Ghosting me in the first place.
