Scam or no scam, email relationships are utterly deadly because reality gets warped. With no actual person in front of you, your imagination is free to invent and fantasise any future scenario it wants.
We've all seen romantic comedies like You've Got Mail, but that is Hollywood fiction.
The only real relationship is two people in the same room, looking and talking to each other, preferably over dinner.
An unknown person in an email, however sweet-talking they are, is still a colossal unknown, with your mind filling in the blanks.
There's another old expression: talk is cheap. It applies to romance, it applies to scams.
As a person who met his wife through internet dating, I can assure you it works, if you are prepared to be brave and put yourself out there.
Romance scams work because people are lonely. If you're lonely, do something about it.
Go online for the right reasons, ignore those who write in capital letters and weed out those who can't even spell their own job title. Take action and go on a date. Don't wait for a heartless scammer to find you.
