Then OP would have to work on finding more time to spend with them, and a lot of other comments address possible ways to improve this.
Personally, when my partner complained about not spending enough time together, I increased the time I spent with her, and it didn't help alleviate the frustrations she was feeling. She thought that what mattered to her was Quality Time, but it was really hearing Words of Affirmation that was important (I see a similarity with users who say they want a particular feature, but really just want to solve a certain pain point). Only when we figured out how she feels maximally loved was I able to use the time I spent with her effectively.

I thought maybe OP could be in the same boat.
