''Sorry to be vague, there was a little round piece of what looked like poo in the sink, obviously I thought it couldn't be and must be dirt or something, so I ran the tap but it didn't go away. I asked hubby 'what's this in the sink' and got him to come to the bathroom and he immediately looked really guilty and sheepish and said he'd been gardening, it must be a piece of dirt, so he pushed it through the drain. He just looked like he'd been caught red handed.''
Couldn't it just be some clay soil from your garden? Perhaps he just looked guilty because he thought you were cross he hadn't cleaned it up. I think you may have jumped to a conclusion that might not be right.
''Things going mouldy - he puts clean laundry away while it's still damp to help haha, wet clothes folded up under the sink, and he hangs his bath towel to dry over the bedroom door but the wooden door is now mouldy because his towel is so sodden, some clothes and towels and bedding I've had to bin because it's gone mouldy''
The laundry thing just sounds a bit clueless, wasn't he just trying to help? However poor the execution! Folding wet clothes a bit odd granted! Loads of people I know hang towels over doors, his towel must be really really wet to do that to the door?!
''I don't usually clean light switches and sockets but since we got diarrhea thought I should to be on the safe side. it's only the baby and i who are ill, he's fine''
OK fair enough. If it's only you two that are ill though, how is it his fault? I'm not sure this is relevant to the rest.
I still think you're making a mountain out of a molehill, it doesn't sound like he's doing it on purpose to annoy you.
