He told me off last night because my hairdresser was in his side of the room so he’s not being his best self right now.
"Told me off" is a very revealing turn of phrase to employ, OP.
How dare he? & what is "his" side of the room? How does he get to commandeer a side of a room, which you are "told off" for entering, IN A HOUSE THAT YOU OWN?
To top it off he’s arranged for me and his mum to take the kids out today so he gets some time to make the cake.
Oh, he's arranged it, so it is now written into law that you must obey.
Because although he knows (he ought, you've told him enough times this week) that it is impossible to do academic work while looking after 4 kids, that's FINE & you have to suck it up.
But you also have to suck up the childcare when he is baking a cake?
Why can he not manage a simple bit of cooking unless the children are removed from his lordly purview?
I don’t want any of the replies to be right, I have to stay in this relationship for another five years at least.
Do you? Why?
Is that the same kind of "have to" as you "have to" take this children out with his mother?
The kind that exists only because he expcts his instructions to be obeyed?
It’s depressing to wake up to it being torn apart on mumsnet.
Dear OP, nobody wants to depress you. Just help you benefit from 100's of years of collective experience from the wise old bags who've been there/done that.
But when you say things like "I feel gaslit", people are going to feel concerned.
When you say "I have to stay for 5 years", people are going to feel appalled that you are trapped.
When you praise your DP for paying for childcare & describe that as a big deal for him, you are showing us the power dynamic & manipulation going on in your relationship. 2 of those children are his - the very least he can damn well do is pay for childcare!
He lives rent-free, & you pay for all the food ffs.
And when you tell us he can never be wrong, but presents you with wilted lettuce instead of acting like a parent & buying party food for his kid ... quizzes you about your academic work despite being told it's impossible this week & the questioning is making you feel like a failure, yet he keeps doing it ... it's clear that he is undermining you.
Please see the PP comment about a truckload of sand being dumped, preventing you from opening the door to your academic life & new career. Why do you "have" to stay for 5 years? What the hell is going on with that?
OP - I'm not having a go at you. I'm just wondering why you are getting the shit end of the deal, & accepting it.
