IOW, He enjoys OW tirades. Not that he says, Whoo Hoo. He'll probably roll his eyes about it but deep down he needs her roller coaster of emotions to feel stable.
I don't remember your Hs history. I'm guessing his childhood was much the same. Roller coaster drama.
In my IC I learned that I thrive on drama (as did my H) which is why I would sometimes create arguments when there was a lull in the relationship. H didn't do the same, however he didn't feel uncomfortable with them.
It all goes back to how we need to live a serene life. That's it's not healthy to create unnecessary drama. (I'm turning this around to you more than H)
Remember when you kicked OW chair at your daughter's concert. Believe me, I woulda been there cheering you on but that was a great example of creating unnecessary drama. In this respect, you weren't very different from the drama OW created at the coffee shop. So do you see how you and OW are alike and H feeds off of that.
He needs to discover this on his own. He needs to want a healthy serene life. You need to do the same. (as I'm sure you're working on now) This experience has taught me so much but most importantly that a boring life (serenity) is better than a soap opera life (chaotic).
I don't want to lead you to believe that if you find serenity he will gravitate towards you. He may, he may not. More than anything do it for yourself.
I hope you have a GREAT day!
