I Know He's really Gay..

Hiksss...What should i do ?there's so many reason, why he keep silent.Last weeks, i've been read his sms. Too many signs of showing he's a gay. I knew it, why he not married yet.Dirty 'talk', men by men.BUT...nothing i can do..Eeryones have their own way. But my big question is, What will happen for our friend relationship... it could be change....or still walk on way...?I'm just ordinary people
