Boyfriend too family oriented?

My boyfriend almost always chooses his family over me. He will make plans with me than tell me last minute he’s doing something with his family. It’s been three years, I’m more than ready to move into our own apartment & live our lives together. It just seems like it’ll never happen because he’s always caught up helping his family. I just feel like I can’t progress with him. He goes back to school complain about not having a job, fails his classes, gets a job, quits the job than promises to do better in school. It’s just the same cycle over & over again. Ughh im just over it. Advice please he’s 22
