Desparation. What should i have to do?

Hello, me n my bf we are planning to get married soon. Every one is agree with us. We were trying to settle in our careers and right now we are on the way for it. I am a computer teacher in international school. In my school working hours are for 9 hours. It's too much but I don't have another option that's why I am doing it. My bf also have a class in mornings n after that he have a job. But he always thinks about me on his work. I am not able to call him in a whole day because in my school phones are not allowed in working hours. He always complaints me for my working hours. Daily he used to fight with me on this topic. His situation is worse now. What should I have to do ? Please help me. I really want to be with him. But not like this. He always told me to get settled down in life n when I am settled down then he starts fighting on Timing issues.
