Does romantic love exist?

I used ot have this idealistic notion of love, even believing myself to be in love with people at points, but somewhere along the way I become disillusioned and depressed with the whole thing. It's not that I expect them to be perfect or love to be perfect, but the feelings I have for people go completely and I feel like life is dull and pedestrian again. Am I just really immature and this is in fact how life and so-called "love" really is?
