Are you owed a deposit on the one you're in? If your boyfriend has buggered off, will the landlord give you the money instead? I'd try citizen's advice if I were you.

Hey - what a rough time. How are you feeling about your boyfriend moving out? Was that his choice - or yours? You have experienced one of the most traumatic situations - the break up of a relationship -and now you face one of the other biggest - losign your home. no wonder you are feeling really stressed. What are your options? Could you get someone to move in and share the place and the rent and convince the landlord that you are a good tenant? Can you go and stay with a friend for a while - just to give yourself some breathing space? See if you can breathe deeply and see if you can see some alternatives. Happy to help you think through some ways forward. Take care.
