boyfriends avoiding conversations?

Noah
So this isn't a really serious post just kind of a peeve. 
So this morning my SO was looking for jeans for work while I was still in bed and I didn't know where I had put them so I get up to help him and he starts like tossing around all of his clothes that were neatly folded and I got so upset because I take the time to fold his clothes so they're decent for him and he just started throwing it around. He asked me what was wrong and I explained it to him and his face told me that he understood but instead of apologizing he said "the jeans were over there though, like how'd they get there??" And I was like......... "were not talking about where the jeans were, we are talking about throwing the clothes around " and he kept bringing jeans up but 
I guess the point of this post is to ask if anyone else's SO does this? Avoids topics? Maybe it's to avoid further critiscism or to hide that they're embarrassed? But I've never understood this trait so if anyone has any ideas they would be appreciated
