Why Does Everyone Think My Best Friend Is my Boyfriend?

Julie here! There was a new kid that was living next door to me named Luke. I've became very good friends with him. We are best friends. I'm a girl and he's a boy. Like we are in the same cl [I'm only in fifth] When the teacher says to get partners we pick each other! Everyone thinks we are dating. Today a boy that I have a crush on came up to me and was like I like you but it's too bad you're dating Luke. And I'm like "nooo! we are just best friends". And Luke is known of the hottie of fifth grade. A lot of girls like him but think I'm dating him! It gets annoying. My best friend- that's a girl named Kerry is the only one who believes us. I mean all we do is sit next to each other, pick to be partners with each other, and hang out with each other. Sometimes he comes over to do homework. Today we were talking and he's like how about if we do go out? And I'm like yea. We know each other pretty well. But we're afraid it will ruin our friendship! I MEAN I TELL HIM ALL MY SECRETS. Do you think I should cut the time I spend with him or date him and make a promise if we break up still be best friends? -Julie a.k.a Jasmine's sissy. <33 bye
