What does it mean when you dream that your spouse is cheating?

It could all just be fears of yours taking form in your dreams

Dreams provide information about the dreamer through symbols. This dream suggests that the dreamer feels abandoned by the spouse. The "cheating" might represent anything that takes the spouse away from the dreamer. This might be anything from working too much overtime to spending too much time with family, friends, or sports.

It generally means that it's something your scared of. That if it's happened to you before in the past. You fear it will happen to you again.

That you should watch out for any other signs that your spouse is actually cheating on you. Maybe its a warning, maybe its not. just watch your back and keep all your valuables locked up or hidden until you know for sure that the one you are with isn't planning on leaving or cheating you. EVER!
