To take your original statement that When I try and explain that I'm just stating a fact, not blaming anyone he accuses me of gaslighting, I have to ask if it was that you're "just stating a fact", then why were you stating any facts, why were you stating that particular fact, why do you think stating a fact was helpful, and what did you hope to get back from it?
I am all for not second-guessing people, and I always attempt to take things at face-value, however, there was a reason why you stated this fact, and if it wasn't to make out it was your husband's fault then I'm clueless as to what it was for.
If it was to state a fact for facts-stating sake, you could have said "It's dark" or "My name is Aliceisagooddog" or "Well that's one for Mumsnet tonight", or anything else for that matter. But you didn't, you stated that the child never falls over with you, then came on here when your husband took the hump.
FWIW, what you said is like nails down a black-board to me, because I grew up in a home where this was a constant expression to absolutely anything I had done or attempted to do, or attempted to use, that had either gone tits-up or was unsuccessful.
Sometimes the inference was that I had caused the problem. Sometimes the inference was that there wasn't a problem and it was me being thick. I never realised how deeply I was affected by this rudeness until one day as an adult at work (I would have been about 21) I mentioned to a colleague that I couldn't get any hot water from the tap in the kitchenettte. Straight away my arsehole of a manager piped up "well it was alright when I used it", and to say a red mist descended was an understatement - I wanted to slap him round the face.
He could have just explained that the water heater on the wall was a storage type and not an instantaneous, and that he'd possibly used all the hot water, but no, he had to make the point that there was nothing wrong and I was a thick bas*ard.
So, again, I ask you, what you hoping to achieve from stating your fact?
