Here's the loop.
My wife gets stressed with son who potentially has PDA, she is fatigued and tired and is unsupported (her words) I try to look after kids as much as possible, but the mental load of kids health and home education falls on her shoulders.
I don't fill her cup there's no connection.
When were out she'll get stressed and overwhelmed with my son complaining he's bored or saying horrible stuff about his sister or hitting her.
I won't give my wife the empathy she needs, your life is hard it sucks, you don't get the support you need.
I take the logical approach at least to me, and ask her to walk away and take a break as I just want her to stop being angry at me and the kids and swearing at us.
Normally she finally blows when I say hey you dont want to do this , you wouldnt do this with your parents or someone else her.
Then she stomps off shouting scarring the kids that she wont come back she's leaving that I must leave home, the kids are bursting into tears, I console the kids, eventually she comes back.
I get it she's stressed and impacts on me like a shark rolling its eyes back and biting you, there is no talking to her she's in flight or fight mode.
The only way that has any impact is just blaming me for everything and saying how unfair life is for her.
Whats going on what am i missing
