Sorry, but I would take exception at ANY person who didn't learn from their FIRST laundry mistake. When I started washing my own clothes at 16yo, I made ONE fuck-up. Of putting a chenille jumper in a washer-dryer and not taking it out before it went through the drying cycle. Never again. I am now 30yo and have never done anything so twattish since. I educated myself on what the care labels meant.
It was one of the issues that ended up driving a wedge between me and my ex-P. Because he was seemingly incapable of taking in ANY information to do with laundry. Yet could learn new skills at work after being told just once. It wasn't important enough for him to bother with, because he had me to do it. 
.
It got to the point where not only did he refuse to DO any washing 'because he was scared of doing it wrong and ruining something', but he wouldn't even pick his clothes up from where he dropped them - even if that was somewhere dangerous like the top of the stairs when we have dc. I picked up after him for ages - then I sat him down, had a talk with him, and he said he would improve. I told him that I would no longer be picking up his clothes.
Eventually, I had to cave, as there was a pile over 2 feet high AT THE TOP OF THE STAIRS. And another 2-foot high pile at the end of the bed, which was causing me to trip over EVERY NIGHT while holding baby DS3. So I would put them on his side of the bed. AND he started shouting at me when I refused to wash anything that wasn't in the laundry basket, and he had no clean clothes. Which was laughable,as even my (at the time) 7yo DS2 WITH SN could manage to put his clothes in the basket, and understand that they wouldn't get washed if they weren't there!
We ended up splitting up 7 months ago. I just couldn't take it any more.
There's NO WAY I am going to run around after another adult who PRETENDS to be incapable wrt clothes washing. He is managing perfectly fine with it now he lives away from me. So he could manage it perfectly fine when he WAS with me.
Very controlling behaviour, IMO. Not bothering to make the effort to educate yourself on how to do a job PROPERLY. I'll bet if he had to take a job where he had to learn new skills, he wouldn't just say that he can't do it. While yes, buying replacements is all very sweet - he KNOWS you don't have the money to spare, so is putting the onus on YOU to decide to take them back for a refund (to be the RESPONSIBLE ONE). He is abdicating himself from being a responsible adult in your relationship. I would NOT put up with that. He SHOULD have discussed with you whether you wanted a replacement, what replacement you wanted, and whether you could currently afford a replacement.
By going out and making a 'grand gesture' of buying you 4 new jumpers - he is trying to shut you up. Because if you complain about it, he then feels he has the 'right' to be annoyed, because you are 'throwing his good deed back at him'. Regardless of the fact that you are unhappy because 1) He ruined your original jumper through carelessness and can't be bothered to educate himself on how things should be washed (not his job?) 2) He made a 'grand gesture' of buying you 4 replacements, when he KNOWS you are short of money (being irresponsible), and 3) Not discussing it with you first.
Trois - I don't think that is being 'emasculating' at all. Having the expectation that your partner sees housework as being just as worthy of educating himself about as the things he has to do at work is NOT emasculating. Unless you see housework as somehow lesser to paid employment? Which is just perpetuating the myth that washing and cleaning is just 'womens work'. I wouldn't stand for that from my DS's, much less someone who is meant to be my partner.I would actually see it as MUCH more 'manly' for a man to teach himself about care labels, understand them, pay attention to them, to apologise for any mistakes he may make, and to DISCUSS replacements rather than just assuming that he knows best for me.
So, he's lost his job. In my world, that would mean that until he found a new job, he would be expected to do his FAIR SHARE of housework, and to do it PROPERLY. Without moaning. Without fuck-ups. And if he DID make a fuck-up, he should apologise without sulking/grumpiness/claiming he somehow can't do it/ making grand gestures of replacement items that he KNOWS we don't have money for. AND he should be financially responsible. Anything less would be a problem for me.
I don't have high standards - just expect that I am not treated badly, as I am worth more than that. I now expect to be treated in the same way as I treat a man. Never any less. I'd rather be single as I am now than put up with any more relationships where I was treated like a skivvy and expected to do all the 'womens work'. Because it ISN'T women's work. It is HOUSEHOLD work, and all adults in the house are capable of doing their fair share.
