Been there and the truth is, he needs to learn how to balance it all. If he can't do that, then he's not ready for a relationship. No one should have to fight for quality time, it should be mutual. You both should want to spend time together. Sometimes when u stop paying him attention, he will come to you. And if he doesn't, well then, there's your answer.
I just saw ur btw... lol. Well then you two need to have a serious talk. Communication is the key. He has no room to talk or get upset. He if he spent more time with u then he wouldn't have anything to worry about. Like I said, he needs to learn balance.
