Who To Move In With?

I'm stuck in a rock and a hard place. Thinking about next year's living scenario, I can't decide what to do. Some of my friends want me to move into a 5 bedroom house with them for the next year, but there's a possibility that my cousin, who is also my best friend, won't be able to live with me then. The big problem is im not sure if I want to live with a bunch of people because there's no telling what they can do, they might decide to have a bunch of people over when I don't feel like doing much or something of that sort. I also am a very clean perosn and like everything put away and clean, but I don't know if my friends will pick up after themselves or even the little things like doing the dishes and what not. I don't know if I just want to live with my cousin eathier because there will be times where we don't know what to do and it can get boring. The upside to living with him though is that we only have to get a 2 bedroom house and that would make it much easier for our home life I beleive. At least I still have 6 months to think about it.
