Is Long Distance Relationship Worth It?

To me, i believe long distance relationship is a big sham by one of the party involved. It might be the guy or the babe but one party is definitely playing one party. How can you explain a girl in School in PH riding/sexing another man while answering the call of her supposed fiance in lagos saying "Sweetie, i miss you, I love you" while the joystick of another man is still inside her?? how can you explain another married man harboring a young girl in his home while his wife just took a trip to South Africa. Nairalanders.. my eyes have seen, my ears have heard and what more should i say? Is long distance relationship really worth the stress? knowing fully well that one party would cheat? and why do people involve themselves in long distance relationship? Is it because of their low self esteem or timidity? mind you, I have enjoyed the benevolence of long distance relationship it ended well but not an happily ever after well.
