Now that I further understand what you was trying to say, I think it's a more normal feeling then most here would care to admit. As Teadrinker already said, it's like an attachment to a movie character. You love them, but you are not in love with them. So as far as that goes it's perectly normal.
And also, as was stated above again, being warned about falling for someone OCC while IC, quit can be a slippery slope but hey,mothers have done it. Just go with what you feel. If you feel that the other person may feel the same way, go for it. Just be prepared that they may not feel the same way.
As far as OOC friendships go, I'd love to be OOC friends with anyone I'm IC friends with. So no harm there.
