I found panties in my husbands center council....he claims are mine but I don’t recognize them....

So I was moving my husband’s car yesterday and my curiosity got the best of me, I opened up the center counsel and found a pair of panties in there that I didn’t recognize...he immediately tells me I’m crazy and that they were MINE!!! From a year ago when he still lived in his old apartment. His version is that all the times packing and moving putting his cloths in his car that they were in with his stuff, but a couple months ago when we went camping those were not in there. So if they were in fact mine why didn’t he just give them to me? A whole year? I don’t think so he’s articulate with his cloths there’s no way he had those for over a year lingering in his belongings...plus I don’t recognize them. I need some fellow opinions
