Family: He needs to do more

Hello all, so I'm having trouble wrapping my head around this thing my family keeps asking of me and my boyfriend.

We've been together 6 years now. My boyfriend works in hardware, and since we started dating he's moved up all the way to a management position at his store. At first, my family was supportive but hesitant which I felt was okay for like the first couple of years but now it's starting to drive me crazy. Lately within the last few years or so, my boyfriend who owned his own house to get away from his family and start his own life gave up his house to his sister and her new family to help them live in better life conditions and came to live with me and my family. He pays his bills and rent on time, helps me fix my car if needed, tends to the lawn when it gets messy and basically helps me when I need it. But lately my family won't be straightforward with me. They only talk about it to me when he's not around but basically they keep saying that I need to make him do more for me. And it's been like this for the past few years now. And anytime I ask them directly what do they want me to do, they either go silent on me or they don't tell me directly what they need.

What do I need to tell him to do?

I feel like now they think I'm trying to make excuses for him, but lately his work schedule has no sense of time and neither does mine to keep track of everything. There's a few big issues with my house that neither he or I can afford to fix at the moment. What should I do?
