my little girl inlove?

Hi Dear, my name is Olivia, I have a 6yr old little girl, to help my husband's brother we accept him and his family to live with us, 3 yrs passed since then, they have an almost 7 yr old son and my doughter started to feel to close to him since then but he is always fighting with her,he tries to be always, first, the best, the #1 in everything even when my doughter is not racing with him, the thing is that I just found a little note she wrote where she draw a picture of him and her and wrote, "I love you, I like you, I know you like me"

What do I do, how do I talk to her???  what's the best for her and me in this situation???

Thank You

You really do not have to do anything about this. If you wish, you can mention that you noticed the note and 'it sounds like you like your cousin and you wonder if he likes you also'. Then see how she responds. I think you are reading too much into the note. What do you think?
