I prefer living alone, but sometimes it's nice to get out of that vacuum. I've never been married so I'm not sure how that'll pan out (if it does). I know I don't like living with others that much and I think it's because there's too much of ME and not enough of them.
Ideally, I think I could live with a male partner with whom I'm totally committed (and he's totally committed to me). As in marriage, as in "death do us part." That's the only way I see it working because I can totally be myself without repercussions - and he would understand my ways (and I'd understand his). It would take a lot to get there, though. I'd need some time to bond with him before we got to that point.
