Should i still be his friend?

Jack might be going through something in his life that he just can't talk about it with a girl even though you are friends there are some things that a guy just can't talk with a girl over. You seem like a very caring and understanding person, don't let him go just stay in the background and be there if he needs you. Even though you are still his friend he is thinking of you. Watch the movie Harry and Sally, it answers alot of questions.
