I feel I'm being clingy and I'm telling lies, never had a boyfriend before..?

This guy i know he likes me and i like him tooo but everynow and then when we talk online and see eachother in person but in person hes very shy so we don't talk much just yet, anyway I i tell little lies and I know its wrong and i shouldnt do it but i cant help it like if he goes yeah i love them i have all there songs i go same! when really ive only jus heard of them and sorta like them..and i dont intentionally do it,, at the moment were friends and hes already told me he is a good liar and i said im a bad liar but in life i dont lie only to my parents sometimes. but now ive started doing it to him, im not forcing anythinggg it just comes out sometimes and i need to stop! =/ anyone else do or done this and how to stop! & I beacuse we talk to much I always initate the conversation he does enjoy it and ask questions and I do but sometimes i feel im clingy and he tends to ignore me but recently he goes offline but comes back if im online but when he used to go offline i'd go offline as i thought he was just ignoring me but then i realized hes probably just busy so anyway he enjoys talking to me but i think even thou we have lots in common hes gone off of me abit maybe?
