AIBU to be sick of my 'D'H's mansplaining?

He does it all the time. He seems to think he is the expert on everything. Can't back it up with evidence/sources either. He just 'knows' E.g. we are in the process of selling our house. I mentioned that we can't take bolted on shelves. He is adamant that we can, despite never having done any research. He will then get angry with me and then eventually look it up. After which I've 'misunderstood' him. I'm sick and tired of this. Once in a while I wont back down and we'll have a big argument where I accuse him of gaslighting. He will eventually apologise and promise to never do it again. We have had this exact same argument hundreds of times.

What happened today takes the biscuit. We disagreed over the area equaling 10 square meters. He got angry with me and then looked it up. Which showed him I was right. Apparently I misunderstood him. Thing is, I have a maths degree, he doesn't... so why on earth did he try to argue in the first place.

AIBU of being sick of his mansplaining?

We don’t know if the OP is wrong because we don’t know what was said. If he said they could take the shelves without informing the buyer (like you would be able to for a freestanding fridge, for example), and the OP said ‘no we can’t’, the OP would be correct.

I think it just shows his insecurity. He needs to feel superior to you by being right about everything. Maybe point this out to him.?

Or maybe just ignore and say 'if you say so'

The worrying part is him getting angry.

That is always a means of control, unless he struggles to hold down a job, or has been through the criminal system. In which case, he just has anger issues.

But these men manage every day to have respectful debates and take critism in work.

It's only with the Women in their personal luves that they try to intimidate into silence.
