1) If you could go back and give a piece of advice to yourself in the first year of your marriage, what would it be.
Never to allow another person to have that much control. In my attempt to make him happy, I made the mistake from the beginning of always being the one to sacrifice while he always took. Now, I know to watch the patterns that develop from the beginning because they can be hard to break.
I would say from what you have written that you need to realize that there is more than one acceptable way to do something. Bo can have different ideas, and different opinions, and different ways of doing things and that is OK. You two do not have to be clones who agree on everything and who do everything exactly the same way. I am thinking that you might have been raised with the notion that there is one right answer to every question and that everyone must do everything that one right way. It makes you insecure or uncomfortable if Bo does anything outside of that narrow view. You think that you are just trying to help him and tell him the right way (because his different way must be the wrong way). As he accomplishes things at work outside of your guidance, he could grow to resent your treating him like he can't do anything right without your telling him what to do.
