Over a year and haven't met his family?

My boyfriend and I have been together for just over 15 months.im 28 and he's 34. My family is thousands of miles away, but his is like 30. He visits with them sometimes, but has never taken me. I know it's partially my fault; he's invited me to his nephew's soccer games before, where the whole family goes, and I don't want to go because I work 3rd shift and they're at like 1pm. It just seems like he would have invited me to dinner at his parents or something by now?
