I have, but only briefly. I loved it! I had my first living alone experience after marriage, though. If you'll notice a thread I posted about being afraid of the dark when I'm alone, that always took an effort on my part! But, I did become more at ease with it. I loved being in my own place, with no distractions. (In that I mean, I get more stuff done if I don't have someone there...I hate doing stuff like laundry or dishes if my boyfriend is home, for example!) But, that being said, I love living with someone who is respectful and understands the need for some down time and alone time. I like my living arrangement a lot!
