You made a social media mistake and it is a bad look.
You can right the wrong right now by deleting all the Max Hall stuff from your timelines and reaching out to Max and his wife with an apology, which they may or may not choose to post. Based on how Max has been living his life for quite some time lately, he'll probably accept the apology and maybe even agree to meet with you and break bread. In the end, it becomes a cool moment where you right your wrong and make a friend.
Just some advice--don't know if you or your friends read Cougarboard, but it would be a smart move.
