Long story short, I rented this two-bed we are in five years ago after I left an abusive ex. I live in it with my fiance now and two boys (9 and 11) who I share 50:50 custody of with their dad. When I moved in it was liveable in but my mum and I spent a lot of time into decorating it (with landlord permission) to make it look lovely. The loud red walls were changed to a pretty mushroom and both bedrooms and hallway fully decorated more neutrally. I keep it very clean and tidy.
But I have been telling him for years that we are starting to get a mould problem. It's now got really bad. We haven't been able to open our bathroom room window for three years as it was broken-only fixed literally today. I kept asking him to get it looked at.
He says it's our fault because we have too much stuff and we must keep the heating on 24/7.
I'm really being affected by this mentally.
We cannot afford to move.
Any advice much appreciated.
