Snodderly... I agree, we are probably both tired of justifying our positions. But, the reality is... WE ARE PARTNERS! At this time, he will agree to that. But, he does sit in the best seat, doesn't he? I guess the only way to stand up to a bully is to call his bluff.
I completely understand that both of you would verbally agree AT THIS TIME that the two of you are partners. In an informal setting, that still is not correct. Because as you indicate, he's sitting in the best seat, if the driver's seat is... the best seat...
Again, that is purely verbal, right now, and strictly intellectually. NOT functionally... and NOT legally.
Asserting yourself more could change his position which is why it is so important to either get it in writing, with prior advice from a L (which I know you will get as you've said repeatedly you will get, in advance of any convo with him on said).
or...
accept what is, that you are an employee and creditor, take your wage and loan back, and walk away.
