Hmm… well I could tell that you’re just driving yourself crazy with all these questions that you’re waiting on someone else to resolve for you and this would have to be your friend. From my past experience, guys are straight forward. Have you ever thought about just coming out and just asking him to have a private lunch date maybe? Ask him “would you like to go out with me for lunch, instead of saying hey lets hang out for lunch.” Would you rather find out now and let it drive you crazy and start your summer this way and take things back into your own hands.
