Name changed since outing.
Have been with DP for two years. Just before we got together he put an offer in on a house, which completed about three months in. It’s his first “proper” place to furnish from scratch, having done room rentals etc.
My advice at the time was to make sure, out of all the purchases he would be making that didn’t really matter, to buy a comfy bed and a comfy sofa. Try, test, sit, squidge etc, since you spend so much time on them.
Fast forward to the furniture arriving (we were not living together) and he has a dinky Scandi-style sofa that can just about seat 2 people and a tiny armchair. So only three people can sit in the (rather large) living room at any one time, you can’t stretch out on the sofa, the arms have no cushion. Uncomfortable.
As for the bed, he went from a king size in his house share to a small double. I asked him why he went for such small furniture and he kind of mumbled through it.
Fast forward to a year later (December last year) and I get evicted from where I rent (s21 notice, no fault) and so we decide it’s time to move in. There’s all kinds of weird things in the house that a man like DP would never think to buy- a splatter guard, soap filled scrub pads, tubes and tubes of spare toothpaste/shampoo/shower gel 
It turns out that his mum had basically furnished the whole house and that the tiny sofa and bed were bought by her, put in the house (while he was at work) and he had to give her the money for it. Apparently, she had offered to get “some bits” for the house, since he has a busy job, and just went a bit OTT.
So, the point of the thread. I’m sat on the sofa today, some 8 months later, still seething about how uncomfortable it is and wondering why my DP couldn’t have just put his foot down with his DM (there are boundary issues, it’s an ongoing thing unfortunately).
A label was sticking out the back of the sofa which I noticed, and it has the make and model, and fabric style of the sofa. I’ve just googled it and the tiny sofa and tiny chair cost over £1500. Honestly, it has just ramped up the irritation as to how such a shitty sofa could cost so much and that I now feel compelled to at least get some use out of it, since it cost DP so much.
I was hoping to twist his arm on replacing it soon with a more comfortable one, but I feel bad just chucking a fairly expensive sofa that is only 18 months old. AIBU to still be irritated by a bloody sofa after so long??
