It is natural... It's all about relationships and maybe you get attatched too fast. People on the net aren't always serious and will just disappear one day... In RL relationships work differently, so don't apply those principles to the net. I don't have the answers you are looking for, but it sounds as if you have a need for closeness, a need to be with someone who thinks you are special, but the net is the wrong place to look, although it's much easier than facing the dating game!
