Have I stopped liking him?

For the past 3 months I've just obsessed over him, been totally infatuated, always thinking about him, erflies, nervousness etc. We're friends though not very close and I felt a mutual attraction and often felt that he liked me and today I was planning on telling him how I feel but I didn't get a chance to see him, and I've been thinking about him..and I've realised that maybe I misjudged his character, saw him in an overly positive light and ignored his faults.. I have a tendency to make people up to be better than they are in my head.. Does this mean I'm over him? Lately I had been feeling like the connection between us was a little strained, not how it should be, and I even sensed possible disappointment from him..but I can't be sure that it's not just in my head because the communication is not great between us....have we both gotten over each other and missed the chance to have a successful relationship?
