(Please help) I think my friend likes me but i don't like him and I don't know what to do?

Recently I had an argument with some other friends over skype about if we where too young to date or not. I though we where too young but they said other wise. After a few minutes of arguing they accused me of liking someone in the group. Wanting to end the argument i just told them i was lesbian (which was a lie) and walked off Boy: hey Me:what? Boy: I can't sleep Ive been thinking about someone in are group the person is you Me:why? Boy:I just can't stop thinking about you your on my mind 24/7 Me:that sounds Cliché Boy: I don't want the others to know because some people might be mad. Me: who would be mad Boy: I thought you hated me Me: why would i hate you? Boy: because of the argument between everyone Me:what about it Boy:I thought you hated me but i know theres no chance Me: honestly i don't hate anyone and the lesbian thing was a lie Boy: so there is a chance After that we just talked about random things but not for long. Please help if you have any advice. (I will also be posting this on r/relationship_advice)
