what a position your landlords put you in, that's such pressure. make sure you get your deposit back as at least you can use that for deposit for something else.
councils also should be able to assist with deposits if you find anther private accommodation, did they mention that to you. probably not, as your not effectively homeless yet. Has the landlord given you the notice to quit in writing? if he has take it to the council and get seen and registered, they wont be able to make you a priority, but your still effectively homeless and they're homeless prevention strategy is to support people to find accommodation and not be on street, many councils now, push to get people to find private accommodation and have some estate agents they work with that accept HB. not sure if I'm telling you something you already now, so I wont continue, ill wait to see what your response is.
I know things feel so scary and awful right now, housing is the worst thing for us to lose, please try and remain strong, and like Amaya said make it your mission on Monday to get proactive.
has your landlord definitely gone then, lets hope so, lets hope you get some peace and comfort over he weekend, so at least you can clear your head.
His change in attitude towards you, is probably nothing to do with you, and more to do with him and his guilt at serving you with the Notice, some people dotn know how to act, and so he's probably feeling uncomfortable himself as he knows he could have and should have done it differently. Its speculation, but Could also be why he went of to pub, and also gone out again only staying for ten minutes. Even if that's not the case, try and think of it in that way, as you've done nothing to him, so its his issues. The last thing you need is to try figure out why he's got a bee in his bonnet, just focus on you and staying strong.
its been few hours sicne you last posted, how are you feeling?
