<human>: At the beginning of this year, my husband ("Josh", 34M) and I (34F) joined a Meetup group. 

Recently, there has been some drama and my husband wants me to just ignore it. Specifically, there was a party on Saturday night that wasn't a Meetup event, but was all Meetup people. The hostess, "Annie" (32F), decided not to invite certain people bc of recent drama, and due to space in her home. 1 person that was at the party, "David" (45M) is very good friends with 1 person who wasn't, "Cammie" (21F). I will admit, I did speak to David about Cammie, bc I've been concerned about the rumors being spread about her and the drama it has caused. Both David and Cammie have been guests at my home in the past, and were invited to my recent b-day party in June but couldn't attend. 

On Monday, after the party, David texted myself and Annie normally. However, on Tuesday night he started texting another group member who was at the party Saturday night, Nancy (32F),  and accused me and Annie of saying horrible things about Cammie. Apparently, on Tuesday night David got together with Cammie and 2 others (1 of them Nancy is kind of dating) and they seemed to have spent the night bad-mouthing both Annie and me. Sometime on Wednesday, Cammie unfriended everyone on Facebook. Neither Annie nor I have gotten a text from David or Cammie about the situation, but Annie viewed Nancy's phone and told me last night. I confirmed last night that Cammie had unfriended me. 

So there it is. I want to jump up and defend myself, but my husband says to let it go and ignore David, Cammie, and the other 2 people who are involved.

Can you condense the text into three sentences or less?
<bot>: People have apparently been attacking my character behind my back, husband wants me to do nothing at all and just ignore the situation, to "ghost" the dramatic people involved. What should I do?
