Staying together for the sake of the kids is not a good idea. As a child of that situation I can say that with certainty.

My mother was in love with the man who is now my stepfather from the time I was 2 and she waited until I left for college before she left my father. I never heard them fighting, but I also never saw real love between them and I grew up with no role model of an honest, loving relationship. I'm not saying that's the reason I went through men like Kleenex, but I'm sure it was an influence.
My mother has said for years that she is so sorry she didn't leave sooner and have my brother, myself and step siblings all raised in a house with love.

Giving the toys and the niceties, doesn't mean shit. I had pretty much everything I wanted as a child and it is no substitute for a parent's love and attention.
You can't make your children happy if you're miserable.
