Husband acting sketchy

My husband and I have been going through a rough patch lately and will begin marriage consoling soon. He's been having some payment issues at work and wanted to talk to his boss about it but since his boss has a habit of saying something then claiming he didn't my husband recorded it on his phone. After the conversation he forgot it was recording and it kept going for an hour and luckily caught another conversation between his boss and him sometime later. Well he wanted me to hear the first conversation between him and his boss but as soon as it got to the part where he forgot it was recording he took it off speaker and listened himself and wouldn't let me listen. I asked him why and he ignored me but since things have been so rocky lately I didn't push the issue because I didn't want to have another argument. I have a feeling 1. He's cheating or 2. He was talking bad about me at work and wasn't sure if it would be on the recording. Would you be weirder out by this? He then came to me later and told me I could listen now after he had listened to the whole hour himself😒 Opinions?
