Please answer me on this one I like this boy but the stupid thing is that he is my bestfriend... February 25 2014

Q: Please answer me on this one I like this boy but the stupid thing is that he is my bestfriend brother and he is going to be 19 this year and i 17. Is it stupid of me liking him? And any advice for me to flirt more with him? I Snapchat him alot and he snapchats me to so like he is on my firstplace and i am on his firstplace, so just please give me some advice

nothing wrong with the age difference, as for flirting I would just say be yourself, whenever you talk to him smile a lot and just overall seem interested
