Ask him. If he is your friend, it shouldn't matter. Tell him it doesn't matter to you one way or the other.
You ask.
You ask her.
Tell him you are uncomfortable with that.
You know you are gay if you have sexual feelings for people of the same gender. If you are gay, and you are attracted to a straight friend, you need to move on. You are only setting yourself up for heartache.
You can either accept him for who he is or just leave him alone. You are not a true friend if you cannot accept him for who he is. And don't say he is "a gay" that sounds offensive. He is gay, and he's your friend, so deal with it.
only if u ask, but do you want to know:)
Check their room for gay porn then check how they stare at other people
Most likely no. If he were into you, you'd know it.
I don't know the situation and I kind of do not know what you are asking.
You can not tell if someone is gay. The only way to know for sure is if they tell you.
caring about a gay friend doesn't make a guy guy. It makes him a good friend and a wonderful human being. As for "running to girls," if you know that's a cover-up for sure, then you already know he's gay. Otherwise, it doesn't mean anything.
If you are gay with your friend, then you might be gay, or partly gay, which is called bisexual.
