I'm in this situation OP. It's been years. YEARS. He was supposed to move out and didn't and I can't - there is a 10-yr waiting list for social housing here and until I'm fluent in the language I have no chance of getting a job that can pay enough for private rent (2 kids too). Can't leave the country with the kids without his permission.
It's horrific.
Weekends are awful, school holidays are a nightmare..or so I thought, until I just spent 10-days locked in quarantine with him. That was a nightmare.
People who live in their home country simply don't understand. I try to remind myself that when they say things like "Just get a job and leave him" they're not trying to be insensitive, they simply don't understand the reality - and lucky them.
I have also been accused of being passive. But it's not passive when you're struggling every day. It's that you're exhausted. And if you're not fluent in the language - and I mean at least C1 level - then even things like applying for benefits, if you're entitled to them, is virtually impossible. The rules about renting places can be different. The rules about taking kids out of school during term time, the way the health system works, even the ability to retain your driving license is all different and crucially to understand how these things properly apply to you, you need more than holiday-level language.
As my H has refused to engage with the fact I want a divorce and I cannot get a place to live (I can't claim to be homeless as the house is in both our names) he can do what he wants, so hasn't left. Brexit caused me massive problems, to the point where I had to accept him staying because I wasn't certain I'd be able to stay in the country - but my kids would be staying here!!! Brexit has honestly been horrific for me. Then when it was decided Brits could get a particular visa, I got it. I then got a lawyer and tried mediation but he just wasted the time - stringing everything out and doing nothing he said he would. I ended up having burnout, unable to walk.
I'm finally able to file for divorce this year (as in I have a bit more strength) and have a SHL who seems to have him sussed. No mediation. It's going to be another nightmare, I know it js, but my mental health has been so destroyed by this situation that if I don't battle on, I'll have no chance of a life again. I've been truly broken by this and it's already difficult to imagine how I can ever be happy again, but there's no chance if I don't get out.
