I have seen the same thing with my xh. He had what I considered (and still do now) to be an awakening about 2 ½ years ago. In hindsight now, I can see what happened and put all the pieces together. Prior to that he had some moments of clarity but it never stuck for long. When it was real, I really felt it, it was very different but he still kept running after that. It confused me.
Mine created a ton of damage that was too great for him to handle, and what I have seen since has been dealing with the guilt and depression. I was confused for a while because even after what I thought was a real awakening, he would regress. He acted as though he was ready to face the damage, and I think he wanted to, but he was not at all prepared to face things.
During the next round of connection for us, he was clearly depressed but very aware. I think too aware of what he had lost. He acknowledged things that he hadn’t in the past, like things I had done around my house. He looked at pictures on my mantle with great sadness in his eyes. He had lost so much time, and had become aware of it. He was overwhelmed and decided to run a little more to escape, but he could only go so far. Just when I thought he was a goner for good, he’d come back for more! With each cycle of connection for us, he, and probably I, have learned and gotten stronger.
It did seem like what he had learned or “awakened” to, had been forgotten, because when he felt cornered he’d spout off some serious nonsense. I have learned since that he had not forgotten at all, it has just taken some time for him to process all of this. I am learning from him just what a huge role guilt has played. Fear has also been a huge factor. When his feelings for me started to resurface, it overwhelmed him, and I saw how afraid he was of whether or not I would accept him.
I hope this helps. My xh is just now really starting to talk about things. I hope he can continue to make progress. The progress he has made lately has been very impressive, especially in acknowledging his guilt and how it makes him act. He’s really frustrated with what he has done, and how to make peace with how his actions belied who he thinks he is. He doesn’t understand most of what happened to him. What he does is trickling out slowly.
