Need Advice ASAP!!!

Lynnmarie
Hey ladies, I need some advice. Today I asked my mother if she wanted to attend my anatomy scan appointment tomorrow to find out baby's gender with me and my fiancé. When I let my fiancé know I invited her, he got really upset and said that I should've asked him first before inviting her. He also said that if she goes, he will not be going. I don't even know how to break the news to my mom without hurting her feelings and causing her and my fiancé to argue "again". Please help..... I really don't know what to do and I'm so emotional right now.....
