I left the matrimonial house 10 days ago 

although I love my husband, and I know his 17 Y/O daughter is going through a tough time in this pandemic which is causing her to act out, but I ran out of patience and tolerance when one of their frequent arguments turned physical. she had attacked him and he had responded by forcing her to her room and shutting the door, bruising her arm in the process.

All this occured while I was on a work video call, with an audience of around 10 people, who heard it all. I felt ashamed and violated.

I asked him to leave the house and not come back until they had talked about it and sorted it over phone and cooled off. he did come back a week later and they are on good terms, but it never went back to normal for me. I got restless and intolerant of arguments and sensitive to noise. little things like her sleeping on the sofa rather than her room started to make me restless. I just packed a few clothing items in my gym bag and left.

although I am financially capable of sponsoring myself and the baby on the way if this is really the end as thankfully I stayed employed, but I am uncertain as to what I am to do going from here.

I suspect that she has underlying mental health issues which haven't been diagnosed, and probably will never be addressed, at least not for a long time to come. I dont know if it is fair for me to sign up for years of exposure to this. at the same time, I feel so defeated that my marriage may actually have truly ended, just like that, due to something I have no fault in.
