Just thought I would share ...... my parents were in what I would call, a marriage because of the kids, sort of situation. The didn't speak much, sat in different rooms watching TV, mostly didn't sleep in the same room, and I have no memory of them ever sharing a kiss or a hug in front of me. There really wasn't much fighting at all.
It was something that always bothered me, especially when I saw friends parents interact. My parents were my example of a marriage and my picker was pretty well screwed up for a long time.
Just my experience.
Good luck to you!!
