Why ask the obvious? He’s a man, not a child...a possible cheat yes; but not a child. What we have in front of us is a grown man who possibly made a decision to have sex (or not) with another grown person.
There’s no need in asking obvious—it’s easy to plan and plot an out but harder to harness reality and meet him right where he is at (the root) as his wife.
Off the top of my head I can think of two reasons why my husband might have condoms in his car outside cheating...
1. He bought it for someone he is trying to mentor (or who is too shy to buy it themselves)....
2. He wants us to try using these condoms (we are always looking for something that feels close enough to the real deal) because he doesn't like the effect hormonal birth control on my body and the possible thought of it making it harder for us to get pregnant when we are ready.
In my particular situation, cheating is the last thing that will cross my mind honestly. My husband wears his guilt and fear on his face like a damn sign, and is the worst lair on the planet so I would have sensed something was off... lol... If he was cheating, he also wouldn't keep it in his car cos I drive it when I run out of gas... I'm careless and forget stuff in his car all the time so I have keys etc
Also, unlike me, cheating is a deal breaker for him... the day I cheat is the day my marriage ends... before he cheats, the marriage would have ended for him and in that case, the condoms are just the icing on the cake.. no need to waste more time being together.
