Sorry this is a long AIBU...
Backstory-
DM is a narc (so should 'expect' some lies I guess). DB has severe depression. DB lives with DM. I was always told he had a job, sometimes he did overtime, I got told about a promotion, him maybe working on Christmas Day and his colleagues or work party.
He had a bad breakdown, I asked DM about work etc, she said he hadn't worked there for years, I said "so he's been leaving for work and sitting alone in town?" She said "yes, apparently he hasn't worked". In this time we also found out he had 7 overdrawn accounts.
Now-
I find out DM and DB lied to tell me he had a job. DM said she thought I wouldn't love him if he wasn't employed, I've tried to phone DM but can't get through so have been emailing.
AIBU to expect her to say sorry or give a reason for this? I get she is stressed by DB (and me being cross at her isn't getting to DB as he is somewhere else ATM) but his friends knew and I didn't, in the emails she said it was a 'fight or flight response and because of her tough life she picked fight', she keeps emailing that her ex harasses her, she had a tough childhood and she understands if I want to scream at her and never see her again.
