By keeping silent. Tell him he is right, degagimesh nigeriw. If u don't fight back, he will gradual stop it in 5 minute. Always remember what u feel at the present moment is not real, anger, jealousy, they are not real. But love is real. It continues to live with u, every waking moment of ur life, until u two guys decide to kill it. So Those feeling of Anger u feel at that moment are not right. Was those fights were worth of degrading ur love? I don't think so. Do u remember every detail of ur fight before? I don't think so. So the things that make u angry at that time are just ephemeral, alafi xefi nachew. But u might get along together till death. Always think that. Think u won't remember this fight after a year, but u will keep loving him after a year.
