IZ, you have been reared in a very safe environment for most of your life--protected by a good boy friend--even though he's thousands of miles away--but there was literally no information known by you or by your boyfriend about the real personality of the man who virtually invited himself into your boyfriend's life.

In this day and age, one has to be careful about strangers who come into the home, frankly. With no knowledge of the man' background, it isn't wise to broadcast on the internet what's happening in very personal situations. You know what I mean.

I don't think you need to feel paranoid; you just need to be aware to think carefully about how to manage a crisis when one occurs. It could never happen again, but it
could also not be the end of it all if that man is not out of your boyfriend's life.

Take care of yourself. It's good that you try to keep most of your life personal and private. I've never seen anything untoward on the internet because of criminal behavior; but there's plenty of it out there, including attacks on peoples' computers, for instance.

Just remain alert and careful, but enjoy life, too, please.
