Danae's right.... You THINK he likes you. Don't create drama that is not there If you don't have to!
I am a lesbian but I think a boy likes me so how do I tell him that I'm gay without hurting him or accusing him of liking me?
Unless he acts their is nothing to say or do. You will just end up embarrassing one or both of you. If he does act you act just tell him your are better as friends.
No need to act here. You think he likes you which means you're not sure. I swear, it's like no one has a conversation anymore with each other. If he talks to you and you guys get along, great.. You've made a new friend. If he asks you to go out with you, simply tell him thanks, but you've got a partner, or whatever term you want to use. If he asks if you're gay, then you call tell him. Otherwise, your sex life and preferences are no one's business but your own.
