Susan's right on the mark here.

Affairs are passive aggressive behaviour.

You have hurt your partner in some way they consider offensive enough to warrant retaliation.

Rather than taking the high ground and going to Family Therapy, they decide to start an affair.

A LOT of this is subconscious. They would never admit to wanting to hurt you... but I agree with Susan. A LOT of the affair is driven by suppressed rage at the spouse for things they have done. The AFFAIR aggravates the actual offenses into something epic.

The affair will play with your spouses mind into thinking you are the anti christ and their behaviour is perfectly acceptable.

The passive aggressive behaviour is there, and its legit in my opinion, but no one having an affair would likely admit to it being an act of vindictiveness designed to hurt. In my opinion they aren't even aware that it is themselves.

SOME know it for sure, but I think a lot of WS having affars just let their impulses take control and they just start doing things... the subconscious has taken over full force at that point.

They want to hurt you, but they can't do anything criminal, so they cheat and lie instead... which is viewed by the media in many cases as beautiful and romantic instead. So they get to do something romantic and hurt you at the same time... in their view its a win win. The conscious thinks they are in love, the subconscious is satisfied they are doing maximum damage.

But as I said before, and I think Susan seems to concur... You need to IGNORE him. You are fixated on every eyebrow movement as some sign of info for you.

INTEL is important yes, but NOT from his mood. His MOOD will tell you nothing because its spiking day to day. Forget using his mood to measure your success... that's a road to ruin for you.

Focus on his ACTIONS, not his mood.
