Need some advice?

Me and my boyfriend have been dating for 4 years. During these years he's never held down a job for more than 6 months. I knew he had some charges that he didn't take care of from years ago and at the time was ok with It. Now he's in jail and has been for over a month now. His mom nor his brother has went to visit him only I have. I send him money and clothing also. Today he had a hearing and I was late as hell getting there because the bus driver was driving Miss Daisy and chit. I caught the last part of what the judge was saying and spoke with his lawyer. I just got a job a month ago and am attending school studying medical billing. He wants me to not go to cl on the 22 which I have a test and work, which I have to be at 1 pm. I just got the job and am on probationary period. My cles start at 8 am. He wants me to be there but I have work and school. Will he understand If I'm not there? I told him before I couldn't make It, but he was adamant that I be there. What can I do?
