Jess, I think you should still be friends with him and chat with him all the time. Just tell him you don't feel comfortable with the telephone thing YET. Got to add the yet.
Then, you know, ask him questions about how he meets girls HIS AGE when he is on tour etc.
I saw a thing about how men assume that the attraction they feel for a female friend is mutual and when a woman has a male friend, she also assumes the non-attraction is mutual.
