A good friend of mine, Ms A, mid 30's, recently advertised for a new house mate and after seeing a cavalcade of apparently dodgey applicants, offered the slot to an apparently decent guy. 2 months later, she's essentially holed up in her room. This guy has some seriously strong "single white female" overtones. He latches onto her friends, imposes himself into her conversations with them, does not respect her space, is overtly tactile, makes breakfasts and dinners for her- unasked! and then gets offended when she declines or has other plans... and there's other creepy space cramping behaviour. She has been a down right biatch to him in the last month, has told him to f'ck off at times, but he hasn't picked up any clues or modified his behaviour in anyway. Today she told him he has overstepped his boundaries, has creeped her out and she wants him to leave. He did his block. She locked herself in her room while he ranted and raved for the next 45minutes. He's left the house for the time being - perhaps to cool off. The lease is in her name. What's her legal situation with this guy?
