Just a bit of helpful information, IZ:

If this ever happens to you again, please don't involve yourself any deeper than giving total responsibility to the police. If, for some unusual reason, your boyfriend had been abducted by a psychopath, you could easily have been his next target had you invited yourself into a situation that was dangerous.

Only the police should know about what is happening. That way you insure your own safety (which is in dire straights if an abduction has occurred and you're the closest person to the one who has been harmed).

You are fortunate that this incident didn't turn out to be one of an antisocial or
psychopathic personality's aberrant behavior.

Take care of yourself, please.
