Should there be legal repercussions for cheating on your spouse who is in the military overseas?

Imagine having PTSD from a war, then coming back home to find out you've been betrayed... it's retarded that ppl be like "muh personal freedom" to call me a tyrant for wanting to make this illegal. People who have no empathy for people suffering one of the worst things you can suffer will just be like "it's a shitty thing, but we shouldn't seek justice for those people who got betrayed".
