Do you ever feel ambivalent toward your spouse?

my hubby and i have been married for 23 years and we love each other very much. we were seperated for 6 months and we both changed during that period and have come back to love and respect each other.

That depends, is this a relationship you want to continue? Personally when things are "blah" in my relationship I try to change it or heat it up. I've had my "blah" time, but it usually leads to a fight. Not a huge fight but one that returns our relationship to something happy and fun. I wont lie either I know at times its my fault and other times its his. Either way something needs to happen to change it. At least in my opinion. I mean why live like roommates unless thats really what you're living with, and why ignore it unless you don't really want to be in the relationship. Figure out what's wrong and then either fight to make it better or decide whether enough is enough.
