really upset at my boyfriend

so my bf and i haven't seen each other so i asked him if we can meet up on friday to go to the beach then he texts me saying how his schedule is full and how he won't be in the city. im really sad bc i miss him so much and he is always so busy. last time i saw him i told him how ik that youre gonna be busy the next weeks and he said no i wont ill be free. so now im really upset and i cant really say anything to him bc i know that he is gonna say that it is out of his control. im just really upset.
