Guests who don’t show up

It’s been over a week since my wedding and I can’t seem to shake off the fact that a long time friend did not show up. I’ve known him forever and considered him a good friend. He did not show up nor has he reached out. I reached out to him checking in and hoping that everything is okay. No response. He watches my stories and post stories on Instagram, but nothing. He is in a pretty toxic relationship so I’m assuming that is the reason why. His friend told me that day, “oh he said you would understand and he’s going to reach out to you tomorrow” silence. I find it interesting because we had a friend that always rsvp’d but would not show up to the wedding (did this 4xs) and my friend would talk down to him and eventually dropped this friend because of it. But yet he’s doing the same thing. I’m trying my best to let it go, but it definitely hurts. I don’t mind that he didn’t come, I’m just more hurt he couldn’t even send a text or respond to mine. Am I overreacting?

EDIT: in no way am I trying to end a friendship over him not coming to my wedding. Sorry if it sounded like that but that is not my intention at all, thanks!
