Advice needed

My Boyfriend works one job as a manager of a pizzeria. He works typically 11-12hr days. I work two jobs, I also work 11-12hr days. He gets a full 2 days off work and I rarely do. I have today off and I am spending it packing. You see, we recently got a new place and the only day we have together off is today. I gave up my shift so we could do this together and he ended up having to work in the morning and said he was going to go to the gym after and THEN he was going to help me. It would most likely be around 730pm by the time he came home. I tell my mother...she proceeds to text him and tell him he needs to help. I had already told her I spoke to him about skipping the gym. Was she out of place to say something to him? Am I in the wrong for askin him to skip the gym? Personally I see it as priorities. I would love to relax and do photography all day but I can't. I have things that need to get done so I can ensure the current apartment is clean and ready for move out. So..any advice is welcome. Thank you
