Question! details below!?

So theres this celeb who is somewhat a friend of mine. We talk on twitter (im scared to text him so we DM) and he always responds, but when my friend tries to he always ignores her and deltes the messages. Why do you think he does that? i dont think he would think enough about her for him not to lik here... i know he does it with other fans too, but why not me? is it just because he thinks im chill and he trust me? Now everyones mad at me because my friend he disses told everyone we talk so now everyone is blaming me for him not responding?
