What if you live with someone you hate?I have experience boarding school, living in Nurses homes, living in bedsit land in London and finally had to share a room with someone for 6 months on a course in my 50's. I am a loner to the point I go to extreme lengths not to live with other people. My darling husband has Aspergers and we have separate bedrooms and different areas of the house that we tend to roost. We have enormous respect for one another's needs.
Right, your situation. I would leave if I could. I have run away from so many situations like this it isn't funny. But I was a very broken person. Thing is, why do you hate this person? Why waste so much energy? Set boundaries on the relationship with mutually agreed to areas of respect for each other. Talk to the person if you can. I used to spend a lot of time out walking or plugged into my ipod. Nurture relationships with people you you do like.
