Covid and In-laws rant

HELP.


So my ffil (I work with him) has been out sick for the past 3 days. I asked someone and they informed me that both my future in laws are sick and getting covid testing today (Wednesday 11/11) mind you we get married Saturday (11/14) so I called my FH while at work and asked if he knew and told him they cannot come unless they have negative results to which he agreed. He messaged his parents with me in a group and his mom decided to call him instead and tell him that they planned on coming anyway to which he said he had to talk to my parents. Long story short my parents got in an argument with his parents because they told them they cannot come unless there are negative results. They are now in my FH ear making him feel bad for this decision as he’s their only child despite the fact they are lacking human decency here and would rather people get sick. I have remained firm that they can’t come unless results are negative but it’s been a super stressful day and it’s so close to the wedding. They were sick all weekend but decided to wait 3 days until we get married to get tested instead of going first thing Monday. I just need prayers that this works out and they will be decent humans and only come with negative results.
