Dude...
I personally don't think it's controlling whatsoever to ask her to respect you. Actually, I kind of feel it's wrong if you don't man up and and demand her respect in this situation. You deserve to trust her, and if this is going to be a foothold that may cause a progression of resentment, then it NEEDS to be stopped, and she NEEDS to respect you.
This is honestly quite far from being controlling. Bottom line is you two are married, and if she's disrespecting you by doing this, or even causing you to question why you even have to ask her to not do this, then she needs to stop for the good of both of you.
