How do you know if im in love?

You know your in love when he/she makes you feel happy all the time, and you never feel sad or mad when your around them. And when your not with them you cant stop thinking about them. If your friends dont like him/her and they say rude or mean stuff about him/her you wont care, because you know who they really are on the inside. i should know. ive been dating a guy since 1st grade, and we have never broken up and we are in the 7th grade. we have never been angry at one another. my friends dont like him. but hes sooo sweet and not very cute, but hes polite and sweet and kind to others.i dont care what they think!
