Well I like this boy and he is in my year and I like him we go out most days but every time I text him I get paarnoid that I am harssing him?

Also he likes my best friend she doesn't like him she has hinted .

Also I don't know if this is flirting but when I kick him he crabs me and smacks my bum back OBOUSLY FOR AN JOKE!

I don't know how to ask him out someone please help?

Just tell him you like him, and see what happens then, and if he likes you too, just talk to him, and see what happens next.

He sounds like a flirt, especially if he's grabbing your butt. :P Definitely consider if he could take something as serious as a relationship before you ask him out. Also, guys love to chase girls, so as far as you harassing him by texting him, let him start the conversation. If he wants to talk to you, he will. Coming off as desperate will scare him off. And if he likes your best friend, maybe you can find someone who you will be sure will be crushing on you back. ;D
