Some family members sure have been busy recently. Here’s another: 

This is not the first time my sister in law has done something hurtful to me or to undermine my marriage. She makes it very clear that she expects to be the center of attention in her family. I am now debating to cut all ties with her. I am tired of the stress she causes me, and I honestly would not want to see her again.

What did the sister in law do?
