Yes, and some people are so in love with the idea, that they become obsessed with finding love and they look everywhere for it. This can be both unhealthful and depressing if they can't find love.
Some people find someone and latch on to them in hopes love will develop and find themselves being used. This can cause self esteem issues.
On the other hand, if you're actually in love and the love is given back to you then you have every reason to be in love with being in love.
But being in love with being in love is different than being in love with the idea of love. I hope that makes sense. :)
