First, I don't think that the saturday shopping time together wasn't working. Just that it may have stopped working for your H. And I don't mean that from a personal perspective, rather from a business perspective.
As you noted in your last post, your H appears to have possibly had plans that were different than what you thought. So it is possible that your H thinks that, at least at times like this (is it overly busy right now? season wise, I mean), that the two of you might best spread yourselves out.
Again, I'm simply looking at that from a business perspective and it completely makes sense, to me. I actually think that opens the door up to better "personal time" with your H, after the doors of the store are closed for the day (or season).
On getting mad at you for not doing things his way, I would have to say that's pretty normal normally, and I think is a normal pattern in your business R.
There's a lot going on in the dynamic, even just the way things were operating for the two of you. Again, as though you were a junior partner. Quite often, regardless of that, people have expectations that in order to do something, it must be done a certain way, which is usually they way THEY would do it. So your H will do that until he finally feels comfortable that you can get the results, even if how you do it is not the same way HE would do it.
This holds the underlying TRUST aspect. There's not much more to say on that, other than his trust is showing up as getting mad at you. It is his problem and while it seems personal, it is just something that he will do until he is comfortable with truly letting things go. That's where his apparent desire to control is coming from. His own lack of trust, which quite likely stems from his lack of trust in himself, which possibly shows up in certain "perfectionist" behaviours, as well. And as you note, also appears to be showing up in his constant desire to "learn from the best" and "know the future". Its subtle, but it certainly appears to be the case.
Which brings us to him suggesting to you that he hopes you will take more "charge" and learn from your mistakes. He's telling you... probably exactly what he believes himself... even though he is currently having trouble letting go the reigns... that will change, in time. I've seen that behaviour very often, both in others, and in myself.
He is doing what he wants because although he doesn't trust himself... he trust others (including you) less. So he's going to do it all, himself. In the personality quadrant, that's called a "controller". He'll get over it. In the mean time, he's going to come across as being overbearing regarding your own business conduct and successes/failures.
