He thinks she became too much like him, tried too hard to please him, tried to give him things he did not want but that she thought he wanted, she made him the focus of her life instead of having a life of her own outside of her position as his wife.
This as well. I tried too hard to please my ex, changed my goals and values 180 to be in sync with him, but I did that because we would otherwise be quarrelling all the time. I made him the focus of my life because I felt he did not accept me as I was. I started spending so much time trying to make him love and accept me and keep hitting brick walls that I had no time to 'get a life'. I did many things for him, which similar to Jae, he did not want. I took that as him not appreciating whatever I did for him. I tried everything and nothing I could give he appreciated. Cooking? Yup. Laundry? Yup. etc etc. I thought, well, there's nothing I can do for him to make him appreciate me then. He would never appreciate me or love me. And I gave up.
Before BD, my ex mentioned that he wished I was the person he first knew. Funny thing is, he never valued the person I was when I first met him. He wanted that person because it elevated his status, more so then anything else. I made him feel good. (He was in the dumps).
Also, the soap opera addiction is a form of escape into a fantasy world as the real world hurts and disappoints more than it satisfies. No energy or desire to do anything? Depression. A sense of hopelessness.
The wife not being interested in going to the award dinner? Well, my ex never let me get involved in his business. There were many things he did and decisions he made that he kept from me. I felt no connection to his successes.
The not wanting to take up the hobbies I once loved? Well, who has time for hobbies when my life was in such a mess.
I believe for Jae and his ex-wife it might now be a chicken-and-egg situation. Someone has to take the risk and make the first move or call it quits.
If the ex-wife finds that Jae hasn't 'changed' (I am not referring to pretzeling btw, but as a result of the better person he has become because of his crisis - I hope), she most probably would remain as she is unless she becomes enlightened on her own and decide to GAL regardless. He can choose to wait for her to come out of her crisis on her own (which he seems to be doing), or he can offer her a new and better relationship, and watch her become the woman he first fell in love with once again. Otherwise they may be just incompatible and have to figure out how to work around it or cut their losses.
Hope it helps.
