Student finance help

I’ve recieved an email asking to confirm living arrangements, I’ve called and spoken to sfe asking what they need from me and they said bank statements and tenancy agreement to prove I’m not living with parents,
I don’t have a tendency agreement since I am living with my boyfriend and his parents so we’re renting out one bedroom and what we do is he pays for the bedroom - £250 a month and I pay for little bits like food and toiletries on occasion for the whole household to share and Netflix stuff like that basically and I also send him money ( it equals out to around £250 also a month from me so £500 in total)
But there is no actual proof that I pay rent because we don’t have a tenancy agreement and my bank statements you can just see like the shops and the odd sending of money (sometimes I give his mom cash but again all of this can’t be proven)
Does this mean I’m going to have to pay back my student finance? I’m so scared please help I physically can’t afford to lose my student finance I’m barely getting by as it is let alone if I don’t have it
I’ve been living here since I changed unis in the summer holidays because it was too expensive where I was studying and I had to work aswell just to scrape by, but I can’t afford to work this year because I will literally fail my course hence why I moved unis
