What does it mean when Guy says he is busy?

“Im busy”- Translation: “Im too busy for you.” Unfortunately, he has decided not to put you on the list of important things to make time for. When you think about it, we are all busy in some capacity but we will make time for a phone call, squeeze in a dinner, or a text message from time to time.

Should I call him if he is busy?

If you know your boyfriend is busy, dont call or text him, even if you miss him. If you interrupt him too often, youll seem clingy and hell get annoyed. If youre really tempted to call or text but you know its a bad time, turn off your phone, or go somewhere and leave your phone at home.
