My spouse is also my follower; are my items "safe" with her?

[Severus]

If I gave my spouse (Mjoll) items to carry while travelling, is there a chance that she would sell them, even if she is also my follower? Is there any way to make sure this doesn't happen?

Thanks in advance for your help.

No, she won't sell it, it will remain in her inventory
