Hello Thotful,
You want your family to find recovery. You want a happy and safe family to be involved with and raise your daughter.
Your SIL knows what you want and pushes exactly that image - a wish you yearn for.
But it's not true, is it? If it were true, she'd start with a deeply felt apology.
Happy Thanksgiving Thotful! Dry out the wishbone and keep your barriers up with your fam.
