I totally agree with that idea of my H being stuck in an earlier stage of development. It's like he has not formed any critical thinking skills or any restraint. His gaming/fast food addiction puts me in mind of a teenager, and the tantrums always come out of something stressful like he cannot handle anything without me taking the brunt, like a toddler fires at their mummy.
I found out that his more recent 'I can't do this anymore, I hate you, I can't cope with the kids etc' episode has likely been triggered by a financial problem with his business. He's only just told me about it, but the timeline makes me go 'ah!' But why not just discuss that work problem with me as a life partner, rather than bottle it up then lash out about something unrelated? Anyway he'll never change that pattern so in a way it's good he did the usual thing as it's brought me an even clearer wake up.
I'm sure if I'd ignored his latest tantrum/outburst about moving out we'd have carried on struggling on. As it is, I'm not putting up with it anymore. I've told him to move out before Xmas. He then ignored that for a few days, til I sent him a link to a house for sale locally. He's told me this gave him a kick up the bum and he's started properly looking. Still blabbers on about 'buying land' and designing his own home
FFS just rent/buy quickly, right now, like any other sane person would.
We are actually getting on very well now, well over the past few days anyway, not sure how long it'll last. I think because the pressure is off him to feel bad about his past shitty things he's done, or to 'perform' as a loving husband, he can direct his energy into being a good dad for the kids and is actually being good company. He said he realises the pressure only ever came from within himself, and that caused stress which he couldn't handle if other stressful things came up. Whatever, not my issue, he's not my problem now. While the kids are so young I'll go along with being friends as long as he doesn't use me as his verbal punching bag whenever stress comes up in his life.
He keeps repeating how he wants to be a team for the kids and he has so many fine words about it all, how lovely our separation will be and what great co-parents we will be. I know the reality, like so many of his grand schemes, will be very different. He'll be late to collect/drop off. He needs me to remind him of basic things, so I know he'll fuck up times. He'll want to go to watch football 5 hours away on their weekend and expect them just to go along with him, instead of making actual plans suitable for them. He'll want to game all weekend non-stop, and ignore them or forget to feed them and so on. I would love to believe his words but I know he'll let them down.
He's agreed to every other weekend to have the kids, and maybe they'll be staying over for perhaps 1 night, we'll see how it goes. He's disorganised, selfish and has the brain of a young teenager, so I'm not convinced he'll be having them even 1 night right away.
