I don't think a romantic relationship will be 100% equal 100% of the time. Sometimes people just have off days, and on those off days they might look on their partner more like a friend than someone romantic - yet other times they'll be the more openly affectionate one, too. Sometimes I know I look on some circumstances and think, "Gee, maybe I love x more than they do me right now" and sometimes I'm so in awe of x that I feel guilty for not loving them more. So, it's a two way street.
Either way, I neither like 'loving more' nor 'being loved more'; relationships are fluid and the most important thing is to let them run their course. Altering anything by force can only lead to drastic undoing.
