Aside from lust, is there any OTHER FEELING for the spouse that makes them more than a friend?

Is it only lust or is there another feeling among lust that you can't feel for a friend but only for your boyfriend/girlfriend, husband/wife?

I hope this question explains it well in case my originial question was still understandable.
Lol
