AITAH for hiding from my mother I was separated?

I, 28F left the house and I’m separated from my husband.

I always had problems sharing things about my relationships with my mother.

She’s upset I lived a “ double Life” and didn’t disclose I had left. And she asked “ who’s going to take care of me”

This got me thinking if I should have told her, since she helped organising the wedding and everything.

She knew we had problems but I would assume she thought they were solved as we continued to show up at her house and didn’t show any signs of conflicts or disrespect towards each other?

AITAH?
