thanks fefee and Amoud. Ok i will explain it to my friend. she just was so much upset! not even because of the possibility of her husband's cheating. It can happen any time, with this "I", or whoever. But the main point is that this "I" was her friend! That's what hurts her. And i fully understand her. As i said, you trust some person, no matter who, your brother, your friend, your boyfriend. And this person hurts you, stab you in the back. This is awful.
