According to me, you should continue your relationship with him. If he is a nice guy, respects you and loves you, then you leave him for the reason that he had no time for you. Maybe, he has lot of work in his office. But, instead of thinking about breakup you should talk to him, ask him to give you some time. I guaranteed if he loves you truly, he will try his best to give some time to you.
Always try to remain positive in every situation then everything will get fine automatically.
