I think pretty much the same stuff
Affection - lots of hugs and kisses go a long way to preserving intimacy once you have kids and the sex is less frequent, IMO.
Liking the other person because, for example, they can be really considerate, protective, etc. helps a lot because it's more constant than love
Trust - to be fair, I don't completely trust my dh with money, but have separate finances to limit the impact of that one. I do trust him not to cheat on me.
Respect, politeness and NOT taking each other for granted - except he really p*sses me off sometimes when he demands a cup of tea without even saying please!
Laughter - diffuses difficult situations
Devotion - taking the long term view and not minding the fact that you will be spoon-feeding your toothless dh babyfood one day
Loyalty - backing each other publicly no matter how much of an idiot you might tell him he is in private
Commitment - being prepared to work through the difficult times and draw a line underneath the things you can't change
Time to yourselves, even if it is only to cuddle up on the sofa and watch a film (like we did yesterday)
