Wow, getting this email notification took me back a few years! Sorry to hear you're in the same boat. In the end we didn't split until 7 months later in March 2019, after another go at relationship counselling and when the dc were 5 and 7. I did indeed move out into rented and we sold the house 6 months later when he decided not to buy me out. I also couldn't do it until I got a job, which I did in April 2019. I moved house, started a new job and ended my 10 year marriage all in the same month!
Advice? Be prepared for it to be the hardest thing you've ever done. I was a mess for the first year, especially as exh didn't seem to have any emotional response to me leaving. The kids struggled in the beginning but I established home1 and home2 and we did indeed, and still do, share care 50/50. Something I got some stick for at first (from other mothers, not my friends though) but it's what the kids wanted and what was best. Then the pandemic hit just as I was getting my shit together, so that was fun!
4.5yrs on and I've bought a house (so has he), the dc are 9 and nearly 12, and they're happy. They don't bat an eyelid at having two homes but my youngest does miss me when at her dad's. So she comes for tea once a week. Me and their dad agreed from the start that we'd be flexible to their growing needs, and that's what we're doing. Both are autistic so they need predictability - and dd needs symmetry 😂
Neither of us have got together with new partners (although I've dated a fair bit and just met someone promising) and we prioritise the kids. Exh is autistic and I've been really lucky tbh as he's very reasonable and we coparent very amicably. I still do all the emotional work and decisions, and the rules are the same at both homes as a result.
Would I do it again? Yes. Any regrets? No, I can't, because then I wouldn't have the dc.
I'd advise gathering your support network around you, you're gonna need them. I found wikivorce a really useful website and exh responded better to black and white figures! He paid me spousal maintenance for two years as his earnings far outweighed mine, but I doubt a court would have awarded it. I'm back in my profession so earn more now and am mostly comfortable although running a household on a single income is increasingly tough. Mostly, I've found inner peace and I'm definitely more capable of being happy compared to when I was married.
Wow, that was an essay! Happy to answer questions but hope this is helpful. good luck and trust your gut.
