A man has just moved into a flat downstairs in my building. I live in supported accommodation, so everyone who lives here has some kind of mental health problem, physical, neurological difference or learning difficulty. I came home one day when he was moving in, and was friendly and said hello etc etc. Ever since then he has been overly familiar, it makes me feel uncomfortable and is creepy. He often asks if he's making me uncomfortable and I always say no because I hate upsetting people or any kind of confrontation. I explained that I do not want any kind of romantic relationship, but agreed to be a friend. He does not seem able to stick to these boundaries. He often just happens to be hanging around the garden or hallway when I come home, flirts with me (I don't always notice as I sometimes have difficulty understanding people's motives), accused me of flirting with him (I was chewing my bottle cap, which is a habit I do all the time, he said it looked like I was flirting and wanted him to kiss me - I certainly did NOT) and put his arm round me and stroked my shoulder while we watched a film at his flat (I really struggle to say no or tell people I'm not comfortable - I felt REALLY uncomfortable ). He also sent me text messages (couldn't say no when he asked for my number) saying he missed me when we've only spent time together 3 times in total, a couple of hours each time. I don't know how to tell him we can't be friends because he can't respect my boundaries. I really struggle with saying all of this verbally. I talked to my link worker about it who said she would discuss it with his, and since I've been back it doesn't seem like anything has happened, and now she's away for 2 weeks. I really dread leaving my flat and coming home, and I am worried I am slipping back into old anxieties (I've previously struggled with leaving my room when living with other people). I would really appreciate any advice you might have. Please bear in mind I have huge difficulties with confrontation in face to face interactions. Is this something I could convey over text messaging, or would it be best to try and sort it out via support Workers?
