Need opinions

My husband went to "Walmart" tonight about 90 mins ago (8pm) , and before he went he brushed his teeth, showered, dressed in jeans/polo, and sprayed cologne. He also was rifling through the empty drawer where we keep our condoms (I later found a bunch of our used wrappers in the garbage), and he's still not home. We've been married for 8 months and I've never suspected him of cheating, but I'm concerned now because it seems weird that he went to all that effort to run an errand. I went to Walmart myself and didn't see his car. I know this all points to the obvious, but looking for other opinions in a time of uncertainty. Please help.
