A REAL : Joke of faith

Recently, i got a close conversation. From that i come to know that my heart sat down. I felt broken in from inside. I started to think that the relationship is made with faith and then played with this belief? Has love become a two-letter game? Making fun of someone's is so easy?
I have a good friend who was in a relation to six months. Now that relationship has broken eight months ago. He looks happy from outside. Sometimes he starts doing misery in his own but does not know. When i ask, nothing says just a little bit of relation in relationship. But today i came to know from my closest that the girl when she wanted or was in relationship for eight months. For a while, i sniffed snake. I started thinking of all my conversation. My friend is hiding me so big a thing from me? I did not ask him directly and asked just how it your relationship. He told me with a false smile just do not ask. At that time i came to know that he was broken from inside. She had been played with faith in that girl's confindence. I thought there might be some shortage from my friend. Then i came to know from someone outside that what has happened? The girl is an contact with someone else and during that time she was in a relationship when was in the trainings with my friend.
I felt the feeling of messing up. But the principle of the world is that people play with good people. I am convinced that my friend's trust has broken trust. Did the truth of 'Laila-Majnu' or 'Heer-Ranjha'(Indian lovers) be true or just stories? Nowadays girls or boys, they are making fun of someone's love, but not about love.
