What you have describes as you and H's strengths are a very nice match. Yin and Yang. What you have to remember about that is that is always a never ending chase around and around the circle. What you think is your strength and being a masculine attribute is your perception wanting H to improve that area about himself, just as he prods and pushes at areas that he wants you to improve in.. or at least function in the way that he knows you are capable of and do with others.
I think the business partnership can be a path rife with pitfalls. I know your H is a major pain to you when it comes to 'dependability' and confindance that he wont just up and quit his job. If you read Deida, youll extrapolate that he is constantly striving to be shed of encumbrances and feel free. I would guess that your H would be ok with his job if he didnt feel shackled and beholden to it. Perhaps that feeling could come if he were able to relieve some of the pressure by having an alternative that the two of you were able to bring your respective strenghts too. If he were to commit to your joint venture 100% though he would likely just feel shackled and irritable by that too.
