Feeling so low and embarrassed

Hello all , without going into too much details I just want your opinion .

Me and my husband had discussions regarding my son . I agreed with my husband because I knew my son was at fault . Despite agreeing with my husband he shouted at me front of my ex- sister in law and it made me feel so small and embarrassed . I have been so upset and crying all evening. I know my son isn’t an angel but regardless I love him unconditionally.

Thank you for your reply ladies . I wanted your opinion on - is it ok to shout at someone front of other and make them feel so small ?

I have always said to my husband if he’s mad about something he can shout and scream at me and tell me I’m wrong but in private not front of anyone and it goes both ways .

My husband doesn’t think he’s wrong and I can’t win an argument with him and he will never apologise even if he’s in the wrong .

I’m just fed up with him disrespecting me always as this isn’t the first time it happened and am thinking of leaving the relationship coz he’s never going to change.
