Sounds like you need a General Manager or Managing Partner. With the remaining net you have leftover - you could hire this person, give them a percentage of profits and pay them a solid salary and hire them an assistant and change nothing
This person would handle all the day to day - project management, staffing etc - you’re completely removed
Where are you located?
50/50 means nobody is the boss. Nobody calls the shots. Nobody is in charge 49/51means someone is the boss, someone calls the shots and someone is in charge.
You need a operator agreement in place - this outlines who is responsible for what, where and how - definitive outlines for workload - without a operator agreement, it’s your word vs. his word.
Secondly - partnerships almost never workout because nobody’s work ethic’s lines up with others and often times partnerships end with one wanting out and one heavily invested.
Source: I am learning from the advice I just gave you from personal experience. Currently ending a partnership in a business for many reasons… and the lesson I’ve learned is I’ll never have another partner. Only employees, operator managers who I pay and retain full control over decisions. Nobody else will run my business by any standard that isn’t the one I set

I’d get legal advice separately and ask for a fat salary. Your name, credit and signature have a price
