My MIL came to visit, I'm pregnant with my rainbow baby and haven't posted anything about it on social media so a lot of my friends dont know I'm pregnant again. She's just posted a load of photos of me heavily pregnant on social media. She hasn't tagged me but is friends with some of my friends and I'm feeling upset about it because I wanted to share the news when the baby was born. My husband says im overreacting and I should've said not to post anything if I cared that much, but it didn't cross my mind that she would. My MIL is quite narcissistic and I wonder if she's done it on purpose so she is the one who let's everyone know, but also maybe I'm being over sensitive. Ive had some issues with her previously but don't know if I should let it go? She posted hours ago so its too late to do anything about it. Am I being unreasonable in being pissed off?
