Will I grow to love him??

I am 14 and he is 16, we met at our local cadets detachment and we became friends. He asked if i wanted to meet up so we did, and he was being really kind and sweet. He tried to kiss me a few times but I kept looking away because I was unsure. Then the next day he invited me round his house and whilst there, we talked, we kissed and we cuddled and it was really nice. Then he asked me out and it was really sweet (if a bit cheesy lol) he got paper and a pen and wrote some really nice things about me and then finally "will you go out with me? <3" I've been single nearly all my life and he is the perfect example of everything I wanted; he is cute, older, kind, loyal, funny and I really really like him and I think he feels the same about me. But I'm not sure that i fancy him or whatever. I WANT to go out with him, but I wonder, if I say yes to him, will I grow to love him? and if I don't, I will have led him on and it will hurt him when I have to break up with him. Also, my mum thinks hes 15 and when we hang out alone I've told here there are other people with us, and his parents think i'm 15 too. I really want to be with him but I don't wanna lead him on when he might fall in love with me while im still figuring out whether or not i even fancy him. Can anybody please help me? :'(

To be honest, that is how most relationships are! You won't be leading him on by going out with him. The only way you'll find out if you really fancy him is by going out with him. Many relationships do end in heartbreak, and it is sad... But this could be the guy for you. If you never try, you'll never know, and you may live to regret it. Hope this helps :)
