Annoying MIL, unpopular opinion

I cannot deal with my MIL.

I hold an unpopular opinion that is: just because someone is a grandparent doesn’t mean they get to be crazy and tell everyone and everything details about my baby or pregnancy.

Especially considering I am a private person.

My husbands mom and I aren’t close, I don’t consider us to have a bad relationship but I don’t feel close to her and also she lives far enough way where it’s not that big of a deal.

However my husband wants me to share more details of my pregnancy with her and I’m private and would rather not. The few small details I share she has to voice to all of her friends and including showing everyone our ultra sound photos. Again, it’s an unpopular opinion and I know many of you don’t feel this way - but I just want our private details kept to strictly family only. I only share things with people that I want to know details.

I just can’t handle her. She also asked for a separate baby shower list different than our target registry for her friends. Her friends who we don’t know.

I know she’s excited but why can’t she just respect my feelings for privacy?
