boyfriends/girlfriends living with each other... no Christian example there.

In my opinion if two people (bf/gf) are having sex already, it's NO different or better than moving and living with each other. Living together, at least they share some type of responsibilities and some form of "commitment." Note, I use "commitment" losely.

JinGA, IF I was the child, I would rather spend the holidays seperately with each parent or with just one parent than the mess/dysfunctionality. Years down the road, they may not going to remember much about spending few days with mom and few days with dad (at least not weird feelings about it), but they WILL remember vividly how they spent the holidays with both mom's boyfriend and dad at the same time.
