my friend japanese recently answered this for me >< aishiteru means "i love you" daisuki means "big like" or "i like you a lot" daisuki is used more than aishiteru O.o;

大好きmeans you like people or other things very much,usually uses it in friends chatting and your hobby. 愛しているmeans you like someone very much,use it when you Confession. I love you=わたしは、あなたを愛しています
