coz that guy would like to extent further relationship with you, but u stopped him. He is not sure if u want to continue the relationship or not. He felt the same : u treated him 忽冷忽熱 !
Sex - if the guy fall in love with u, he would like to sex with u, it is just very normal reaction.
Just show your REAL feeling to him. Make everything clear. U don't want or want to sex with him and would like to keep or NOT keep the relationship.
