I am a lone parent and have 2 adult children as well as 3 younger ones. One of my adult children asked if her friend could come to stay with us as his home situation wasn't good(he lived in supported accommodation and said it affected his mental health)I know this friend and agreed. He's here on the understanding that it wasn't permanent and he needed to sort out something with the homeless team. 8months later and he's still here doing nothing to help his living situation. I feel he's taking the piss. My 8 year old is saying she hates him as he winds her up purposely then shouts when she retaliates. He has doubled my bills with his eating habits he takes everything in excess leaving little without a thought that others need to eat. He puts the heating on and has upped my gas bill hugely. He does pay board as such £100 per month which doesn't even cover the extra food I have to buy to replace everything he uses let alone the fact that my other bills have gone up as he sits up all night using my internet leaving lights on and leaving heating on.he doesn't do his laundry he seems to expect me to do it and leaves all his dirty clothing in my bathroom he doesn't wash up after himself and he doesn't even purchase his own toiletries. He barely washes and just sleeps all day to the point I can't even have visitors as he makes them feel uncomfortable as he's sofa surfing at mine.(My house isn't big enough to give him a bedroom) I have given him 2 weeks to sort out somewhere permanent to live as we can no longer tolerate feeling like we can't even enjoy our home without him literally waiting for visitors to leave and making it obvious that he doesn't want them there. He even tried to tell me my eldest cannot come to my house unless I'm here at home which to be honest if she wants to come over she's allowed to as she sometimes likes to be here when I come home from work. He's told a mutual friend that I've been unreasonable to ask him to move out and now he's making me uncomfortable in my own home as he keeps giving sly nasty looks all the time. There's no tenancy agreement or anything but does he have any rights to not leave?as I have a feeling he's going to try to make it difficult to get him to leave
