Work means no relationship??

My boyfriend just got a full time job and I am working a part time job..... that was until my sister got me a new full time job. I’m still working my part time job and I was very supportive of him getting his job and he’s now only focusing on himself. We haven’t heard from each other in 3 days and he keeps wanting me to go over his house but by the time I get off work to get there he’s already asleep so there was no point. Anyways what should I do??
