LDR is not a relationship. Since 90% of what we relate can only be grasped when we are with the person face-to-face, there is no real relating going on across a distance.
Therefore, since there is no real relating, there is actually NOT a relationship.
90% of what you think about this person is your own fill-in-the-blanks fantasy and delusion, and you are making the mistake of believing it to be real.
As for testing .. few people "test" others. If you value someone you do NOT risk losing them by doing things that might drive them away. Only screwed-up judgmental coldhearted people will "test" others.
So if he IS testing you .. run away from him as fast as you can.
Usually what we THINK is testing is not testing.
The person truly doesn't care ... but since we don't want to face that reality, we rationalize and feed ourselves the lie that they "must be just testing" us.
Believe NOTHING that has not been gained face-to-face.
There are predators ... psycho's even .. who prey on gullible people and end up hurting them in very real ways .. blackmail ... stalking ... betrayal ... even murder.
He is not on FB. Uh-huh.
If he is NOT a psycho predator, or playing you .. most likely he is married or has a girlfriend and just uses you for fantasy when his real life gets too boring. Betcha his girl found our about your communications and THAT I why he HAD to "break up" with you. But then he discovered a new way to keep his cheating a secret from his girl.
Honey ... never waste time with online "relationships".
Use online ONLY long enough to communicate a few times and THEN say ... "OK .. time to meet in person at a public place".
And if they don't live in your city, don't bother.
If they won't meet with you in person, don't bother.
If the don't let you into their electronic life (FB, etc) don't bother.
If you cannot confirm where they work or that no female shares their living space .. don't bother.
His webcam is broken. Uh-huh.
He works in Japan. Says who?
He sends you a picture. Since you have never met him, how do you know it is a picture of HIM? Betcha he did not send up a picture of an ugly man.
