Well love is a very powerful word and you don't want to say it unless your absoultley sure about it. Yes you where bestfriends before that so im sure you had plenty of love for him. Sit down and look into his eyes and tell him you love him.
Tell him what characteristics you like about him. When I was 16 my boyfriend was 19 and when I told him I loved him he felt a rush (so he says) and now hes crazy about me.. you don't want to rush into something you might regret.
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.
