How would you handle this family situation?

My husband has a couple brothers. One of them is not a high achiever and is very jealous of everything we have worked for. He tries to cause trouble in our marriage every chance he gets.

Today he text me that he had a stroke and is in the hospital (nothing confirmed, he’s rather dramatic.) He also made some odd allusions towards me and another family member. Understand he has my husbands cell number and they’ve talked off an on since a big blow up last year (so I’m not really sure why he text me instead of his brother.)

Basically it feels like he’s trying to mess with our marriage out of jealousy, and always feels the need to go through me, not his brother. I’ve deleted his cell from my phone, blocked him on social media, and it has worked until today.

How would you handle it as a wife while trying to stay out from between brothers? Am I doing the right thing in just letting my husband deal with it and take all the abuse?

Prior to our blow up last year, I considered this man my brother, but afterwards, I do not, he got really evil.

(Because of drugs and other issues, he’s not welcome in our home.)
