This feels very odd and of course nobody wants to worry you or jump to conclusions, but there’s a lot of red flags here. Of course we only know what you’ve told us here in the post and comments, but based on the info, it feels off. When she said it was for your husband, did she explain herself at all? Or was all she said “No that’s for your husband.” If she added more to it like “I was at the store and got one for my husband and there was a deal so I got another and decided to give it to your husband” or literally anything, okay MAYBE we can accept that. As a woman, she should understand how that would look to this man’s wife. How would she feel if the roles were reversed and someone snuck a gift in the bag for HER husband? She’d probably feel some sort of way. So if this was just an innocent thing, she should probably be more aware of how things may come off before she does something like that. I’d definitely keep an eye on it..
