Explaining to my girlfriend that I will be extremely busy?

I will be working possibly contract or permanent 40 hours a week and homeschooling my kids. I just finished a certification program or will be next week. She wants to spend more time with me, but I don't know how.. this is my first career and second career is my business that I won't be reopening until October due to a stressor of covid. Due to inflation I need 3 incomes possibly 4. I wish I could sit at home and do nothing, but these crazy gas prices , food inflation, and rent rise it's crazy.
