So you do create drama.
You both need to sort your issues. Him going off on one is not ok. But i can imagine he is on edge alot waiting for you to create drama.
Your boredom at being a sahp isnt an excuse for that. As his frustration isnt an excuse for flipping his lid. Even though i can understand, in part, how you both feel and end up doing what you do.
This is what i mean about not knowing eachother. You didnt know how he dealt with anger and frustration. He didnt know you create drama when bored.
You havent really had chabce to be bored i the last 4 years. Throw in sleepless nights and its a recipr for disaster.
One of the problems in relationships can be not really seeing things from the otgers point of view. Especially when one is a sahp.
The sahp thinks the working one is lucky because they get to go out and interact with other adults, drink a coffee in peace etc
The wohp thinks the sahp is the lucky one because they dont have to have the pressure of being financially responsible for a whole family, they dont have to worry about putting together a report by 2pm, worry they arent achieving targets, etc..
The sahp often looks forward to the wohp to come home for some adult company and someone to talk to. The wohp often has had to talk to people all day (even when they dont want to) and doesnt want to come home to full on chatting etc. Maybe wants some head space.
The truth is that life with kids is hard. For both parents.
Especially when they are young. Sometimes we dont comment on how our partner looks, because we are thinking of the other 101 things that need doing or whats happened that day. Or just zoning out for a few minutes while they go get ready. That goes for both people.
If he refuses counselling, not really sure what else you can do. If you stop creating drama, its doesnt meant that he will deal with anger any better.
Unless you can sort this about between you and both come up with a way to change this. Maybe when you feel shit and want to blame him, you agree that you dont say it and give yourself sometime to think about it. When he starts getting frustrated he removes himself from the room and calms down. Then both discuss it when emotions are not as high.
Might not work, but not sure what else you can both do. It could be that you are not compatible in the long run.
