Husband is private and I’m an open book

My husband and I are going into year two of ttc. We met with a fertility specialist today and are taking steps toward IVF. I finally feel some hope and positivity for the first time in months! I want to tell people about this next big step... but my husband wants it to stay private.

He wants all of the ttc process to be private, but I am very close with my mom especially and feel like I’m keeping something big from her. It’s not that I don’t have enough support from my husband and the two mom friends I’m talking to about the process, but I feel a need to talk to my mom about it and he doesn’t want that.

How did/would you deal with one person being very open about these things and the other being very private? I want to respect his wishes, but I also feel a weight from keeping it quiet. Could there be a middle ground?
