I like living with someone so I have the option to socialize if I want to. Luckily I married a man who has the same socialization requirements as I do.
Most of the time we sit in opposite rooms and watch tv and use the internet alone.
We watch tv together quite a bit and socialize when we are in the mood for it.
I would get too bored living alone and having lived with multiple people I know I need my alone time.
