How do I know I'm in love?

ok so im 14 and the guy I love(he doesn’t know I’m inlove)with is 19.Were not a couple but I’ve known him for almost 2mths. We met at bible converence and I know its only been 2mths but it just feels so right,like I’ve known him my whole life. The reason why we’re not together is because I’m in Port Charlotte,FL and he’s in Miami.We both agreed that it wouldn’t be a good idea to be together.He says that he would travel and come and see me we even picked a date for him to come but I had 2 turn it down because there’s no way my parents would let me hang out with a 19yr old they don’t know. If your reading this and wondering way am I even talking to a 19yr old…trust me I dont know at first I heard he was 16 then 17 then he finally told he he was 19 he’s not a pervert or anything.My question is though I grown so close to him I care for him so much,how do I know I’m in love?Am I really even in love or is it just my young 14yr old hormones talking

PLEASE GIVE ME HONEST ADVICE,MYBE EVEN PERSONAL EXPSIRENCES BELIEVE ME I NEED ALL THE HELP I CAN GET
