I'll try and keep this short. We moved into a nice little flat in June and we were happy. Come September we notice spots of mould in the bathroom. By October it had covered everything: walls, our rug, books, the sofa, our clothes . We were religiously cleaning the walls with mould remover, airing the place out despite it being freezing outside, trying home remedies. Nothing worked and it just kept showing up in more places. 

We let the landlord know and a month later nothing has been done. I now hate the flat, even if it got completely renovated I have really bad feelings about the place. 

I have a heart condition and a massively weakened immune system so I'm at risk of mould making me ill. The landlord is aware but still not done anything. Even if we got someone official from the environmental health I still want to leave because the mould has made me hate the place. 

I was at my wits end at the weekend and said I really wanted to move and I had started looking around and even found and place closer to his work. My boyfriend says I'm pushing him and won't talk about it. But it's making me ill. 

He's been a traveller and used to staying in shit conditions so the mould doesn't bother him at all, and his old house with his dad had mould and he didn't care. I'm at a point now where if he won't move, I'll go by myself. But I do not want to offer up an ultimatum.
<bot>: Our flat is really mouldy and I don't want to stay there even if it got fixed up. Boyfriend won't talk about it and says I'm pushing him. What do I do?
