Our condoms are missing

We have a very good relationship. But this past month has been bumpy. We are getting married in August, have decided to stop TTC and not to mention we had two Mc last year. We have a very active sex life. And it’s been short due to our crazy work schedules. So tonight I went to grab a condom, from the pack we had that we have hardly used. They help him last longer. And he told me they were in the drawer and now they are all gone and I’m not sure what to think. He got caught talking to a girl two weeks into our relationship but other than that he’s very faithful. I know the condoms were in there back in October/November. Advice? He said he may have thrown them away.
