Yes I do think that's true. I think they say the same about men. What I've also heard about men who cheat is they need to feel more appreciated. The something "missing" is often appreciation, emotional connection. Or it could just be physical.
I think as I mention in my post, there's lots of reasons people stray. Men & women. I know people judge me for judging, but I can't get on board with breaking trust being "good" for anyone (although someone did point out to me, toxic/abusive situations, and in that case, I totally get it).
