Ok, he can't think of anything that he likes about her. for him to really like her, he first has to know what he likes about her. ask him to really think of what made him like her and what is still clinging him to her. When he realizes that he cannot think of anything, he will forget about her. It also maybe has something ti di with him being totally attracted to her PHYSICALLY, thats a problem and not enough of a reason to like someone and expect it to lead to love. Peace
