To me, I think Susana's H is struggling with the transitions of a 'normal' marriage given that he's 28 years old.
I remember having a little wobble (way before my MLC) after Ms. Wonka and I moved in not realizing that it was a natural progression of a long-term marriage/partnership. I worked through it and recognized that we were experiencing a transition from being grad students to card-carrying working taxpayers (read, "I'm finally a real grown up!").
In this regard, I think that Susana needs to be her H's wingman and show him the way.
Yah...Susana is in the room while we talk around her while she lies prostate on the operating table.
Fwiw, I could be completely wrong here because I'm not in H's head...but I think Wonka's on the money. I think he is going through a panic because he realised "omg I am a real grown up now" - this is just based on some of what he said post BD, and how he has been talking for a few months about how he "can't believe he's an adult", he's so scared to turn 30 etc.
This is in line with what my BD coach thought, along with a possible fear of abandonment and not being good enough which may have led him to jump ship before he could be abandoned.
Wonka, just curious here, how long was it after you and Ms Wonka moved in? And what got you through it?
