Well. I had an experience ones, when I met somebody by internet, and we liked each other so much, we THOUGHT we loved each other. But when we met, everything was different, at least for me, I didn't like the way he speaks, the way he look at me, the way he ate and dress (sounds like only like the appearance, but no!) it really matters when it comes to that special person. I think we idealize people, it's not advisable to have feelings for somebody we didn't meet in person, but not everybody is the same. Blessings.
