My name is Anonymous, I met a guy right back in my final year like 3 years ago, he's handsome caring, loving etc. He never hurt me, always trying his best to make me happy. He has everything every women wants in a guy. Since then,we've been dating, we always had nice time together. So after 3years courtship, we finally got married. Two weeks after our wedding, I realize he is a gay. Should I leave the marriage or stay? please advice me
