Good for your friend! Just remember, right now is the time that your friend really needs you. You need to accept her/him, be supportive, and if she/he wants to talk to you about a member of the same sex, don't freak. You'll get used to it if you aren't already. And I don't know if you would anyway, but if your friend is a member of the same sex and your afraid they will get a crush on you, don't worry about it. (Unless you want them too, then go for it!)
