No, I do not think the internet is dangerous. You missunderstand. I and many of my friends have met people on the internet. I wasted 4 years of my life on a long distance relationship. When we finally got together we had fallen in love with a person we imagined and the reality did not fit the picture. I am not saying that is true in your case. But you should meet to find out one way or another. I think after 1 year that is not "jumping in".
Also I don't understand why you live life in fear. I grew up a witness but I do not believe the end is coming any time soon. Even if it did (yes I do have doubts at the back of my mind sometimes) I would not change what I have with my partner for anything.
