How to survive wedding with just-no-MIL

My spouse is typical scapegoat from family with narcissist, you heard the story million times. MIL is narcissistic, hyper critical and her default communication style are passive aggressive insults.

We are having wedding in a month, most of the family help comes from my side, so MIL cannot hold it over our heads. But my spouse is nervous about her behaviour on the day of wedding. They tend to get in to screaming matches, since he grown some spine.

I’m not that afraid that she could manipulate my spouse into not going through the wedding, but she absolutely can sour the mood, and I don’t want my husband to be sad, angry and self-conscious on the first day he is my husband.

My only idea is get her drunk, but my spouse doesn’t think it will work. What are your tips? How do you deal with your MILs on big events? Not inviting her isn’t possible, FIL is great guy and we want him there.
