If you were my son, I would advise you thusly.
Go back to your own work. Nice of you to step in when necessary, but you got it running smoothly, now, hire (YOU hire) a general/business manager. After a training period, have him report to you once a week.
You don't need to accompany R to shows and oscar dressings or at any time when she is totally absorbed in the fashion shows or red carpet affairs. If she needs a calming presence, hire a (calm) young intern who would love nothing more than to trail around with R and do her bidding. It's demeaning for you to do it. Supporting your wife is something you can do in many ways, but not when your presence is ignored and not when it demeans you.
Rachel loves you enough to understand that you need to be your own man. Ask her to reverse the situation and understand it as if it were she doing what you've been doing. If she can see it from her own perspective, as if she were you, then she should understand.
Good luck, Rodger, and take care.
