anyone's grieving affecting their relationship?

Kirsty
I know this isn't baby/man related but I lost my mum last year I'm 25 now and I just can't get over it I know it's wrecking my relationship because he is isnt some inspector he can't figure out my codes and ther underlining problem and why I'm upset it's not really because he didn't put the bin out but I don't wanna keep saying it's because I'm grieving as that's not fair I have a go at him for everything but if you've lost someone as precious as your mum then you'll know the grief is so unbearable the emotions take over in an argument is anyone's loss for someone affecting there relationship?
