Hes just playing with you. Go with his mates advise. He only likes you as a friend.
Talk to him about it, maybe approach him with one of your friends nearby. Don't fall for anything stupid he might say. Be serious but not angry.
Remember: Relationships are built on friendships, not the physical stuff.
Anyways he either is interested vut sayd your just friends so as not to pressure you or he just likes your company and didn't like the way you kissed or something haha. Maybe he did like you but after the kiss he realized you arent easy and gave up to being just friends?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
