share same bed without sex - married or not?

QUESTION: I live with a friend in a house we bought together. We do share a bed, but we do not have "relations". He has his income and expenses and I have mine. We have our own bank accounts and our own medical plans. We only share a house and the food expenses. Are we considered "common-law" for income tax purposes? I have 3 kids that I support; they are not dependent upon him in any way, shape, or form.

I have to say that if you are sharing the intimacy of a bed with or without sex and own a house together, you would be considered a common-law couple without a doubt.

If you were in separate bedrooms and he had a regular friend and you likelwise, my answer would be different.
