My husband said stuff like “what is the point of my sister hanging around until. My mum has died to kill herself? Meaning why doesn’t she just get on with it

I don’t want to drag up this stuff with my husband but the kind of comments that my husband was letting loose yesterday… seriously
Asking what is the point of her being alive,

This is strictly the kind of thing I get to say
Once in a lifetime
Under extreme stress…
haven’t got to this point myself
My husband had 3 bad emails from her,
Saying how he is a delightful husband,
poor me,
And let’s make sure we never see each other again

So angry with him
