help me!

hi yadhi 

I write this e-mail because I have a problem and you're the unique friend who can help me. my best friend fells head over heels in love with me, I think he is confused :c because we spend all the time together, see movies in my house or in his house all the afternoon, laugth a lot :D, but these last days he hug me all the time and kiss me in my cheek and one kiss in my mouth, after that I feel nervous and he smile and I say him that I need to go and I start to run at my house. what can I do?, I love him like a brother but he love me like a girlfriend . 

thank you 

Melani
