Oh sorry for misunderstanding your post. It makes sense now. You can't just have coffee with her. And yes, if your husband suggested flowers, and he knows the family member he's right.

So, did this event happen because of an argument you had with your husband? It's hard for me to follow, I apologize.

This sounds very stressful. I hope things settle down for you soon here and I hope you can reconnect with your husband so that any mistrust you have is removed.
