Slowly:

I had a conversation about this very thing with my H not too long ago. He told me something but I knew he was leaving part of the story out. It wasn't something major but I pointed out to him, you said this but I know there's more to it. His response - look I'm a guy, I'm not that detail oriented. I'm not trying to lie to you or leave things out, I just don't think about every little detail.

Could it be he didn't leave out that couple on purpose? Maybe he just didn't think about it.
