I went through what you're describing about a month or so back. I asked a friend about it and she told me to put the bike away for awhile and do some cross-training instead to stay fit. So I covered the bike up with a blanket so I wouldn't see her and feel guilty.
Anyway, I guess as they say is true: Absence makes the heart grow fonder. After a couple of weeks the desire to ride was back.
It worked for me anyway.
Good luck!
