How to let my best guy friend now i like him (10 points)?

mos likely, he likes you back. picking you up and taking you back when your hurt- sign right there. cuddling in his arms- DING DING! He likes you!! Maybe you should just get in a convo and ask like who do you like? that convo could lead into it becuas u could guess eachothers and then find out you both like eachother or you can slip it out to him :)
