@KatieRobin, so many of your DH's words are identical to what my DH says to me, with "you are questioning me", "I'm not stupid" etc, we've also been together 15 years ..
Our latest example was when he was clearing the covered passage by the house where various random stuff gets dumped. When I did the first major clearout of it I just did it - but now he was doing it a few months later he got in a rage as he always does when he is doing something he doesn't enjoy but feels he needs to and no one is volunteering to help him - so he kept throwing things on the drive and shouting about living like pigs etc.
At some point he stormed into the house and said he was turning the power off. I was taken by surprise and said but what about the freezer defrosting? It sent him ballistic, wtf was I asking that, and the freezer wouldn't defrost even in 12 hours and so on. To be honest I didn't realise he was disconnecting the power to do some electrical work, I thought it was one of his ideas where he thinks disconnecting the power would get everyone's attention, stop DS playing games etc
When later we tried to talk about it(trying to talk is a new thing, usually he'd be pissed off for ages and I'd be down for ages afterwards), I asked what was so wrong with needing an explanation why power needs to be disconnected suddenly, and he said that it's my questioning him drives him mad, and even he just wanted to disconnect the power because he wants to he can and doesn't need to explain himself to me.
The main difference between my situation and yours I had been married before to my school sweetheart for years and knew it wasn't ever like it, I never annoyed my first DH like that, but of course over the years I questioned if it was me more and more... I would have run as fast as I could from this second marriage but I had no property to return to in my home country, equity went towards house in UK, uprooted three kids and moved here, and I just thought maybe he is simply far more "testosterony" and I'd learn to live with it, maybe swearing doesn't mean anything and I shouldn't take it to heart too much.
He was brilliant with my toddler DS. His parents were very loving towards each other(or more his DF to his DM) so I thought he'd have a good example, mine were divorced...He like any other human being has loads of good points, great at DIY, would give his life for family, we also had our own DC together and then another one, total surprise, on birth control.
By the birth of the second one we both were pretty miserable a lot of the time. Sex was one of the only times of some human connection and leaving everything else behind. The reason we stayed together was primarily my DSis who was the only one I confided in and who was explaining to me over the years how it was mostly me, and how I could become even softer and more loving and how my DH would not be able to respond to true love.
I was a lapsed Christian and resumed going to Church (Eastern Orthodox) where when I revealed my situation due to him hating Church and religion(the only place I actually revealed it, my friends also don't know, feels shameful and also scary to brand a potentially innocent man with an "abusive" tag) they shocked me by saying it was abusive and not something to fight for (as I thought every marriage was sacred even though we weren't blessed in Church etc) I still just feel if I knew it was the right thing to do, I would have stayed, but what if I'm damaging the kids, because I'm persevering primarily for the kids (3 at home still but soon will be 2, youngest only in reception) They love him, hate when he gets angry and shouty but forgive him quickly as children do. ...I nowadays mostly learnt not to feel too low about his outbursts but it's a lonely existence for me and for him, though I've sort of carved a parallel life for myself with my own friends hobbies etc as much as the finances allow...we are early/mid 40s...
I wanted to post on MN, but I knew there's always immediate chorus of LTB here even for minor things, and 9 out of 10 DHs are called abusive... where are the normal men, is anyone allowed any mistakes?.. and I was in the mindset of never giving up and keep trying to find a way to get along amicably, to have a normal conversation without it turning it into an argument. Your post really spoke to me because your DH seems to get annoyed by exactly the same things. He has a go at me, and then says you ask for a fight, you get a fight, and don't make me out to be some kind of ogre. ..
We also bought a house of our dreams just last year which needs a lot of work which we are in the process of doing up very slowly 🙁
We lived in pretty shitty places on an extremely tight budget for years to be able to buy a lovely house and I'm gutted about having to say good bye to it if we divorce. Though I'm worried for the kids more than anything....
