TY for the suggestions...I am trying to have a little fun when I am not distracted! I am trying to be quiet while he slowly begins to feel the discomfort of a quiet house with no kids and no maid service (his wife).
Good for you! I know that BPD/NPD behaviors can be extremely distracting, and therefore you might need to make the conscious choice to re-focus on self-care. For me it's the best way to stay balanced, and to get out of the FOG. Having a life and connecting with friends outside the familial chaos can help me reconnect to the "real" me and dilute the ill effects of a sometimes dysfunctional family system.
However, I really wonder if your son will feel much discomfort with no kids and no "maid service." I'm pretty sure that the pwuNPD in my life didn't mind the change one bit. In fact I think he liked living alone, because he could do whatever he wanted whenever he wanted, and didn't have anyone's presence to constantly remind him about his unfulfilled obligations, let alone to nag him. Though I think he originally liked the "maid service," I suspect it was less about convenience for him and more about showing off to other people. For example, when his wife hosted parties, he enjoyed giving tours of his new home, using exaggerated descriptions of amenities: "cargo bay" for garage, "wine cellar" for a wine rack located in the basement, "man cave" for the TV installed in the corner of the semi-finished basement. I don't mean to be critical of his home or his wife's homemaking skills, but just underline the "performative" nature of his personality. Everything about him seemed performative, highly attention-seeking. The "maid service" seemed to be valued only to the extent it got him more attention from people he wanted to impress. Similarly, he seemed to use the kids to get attention too, mostly from his own parents.
Alas, these days, I think the "maid service" typically most valued by singles has morphed into UberEats. Since the NPD in my life can order whatever food he wants and have it delivered straight to his door, he's comfortable. He doesn't care about messes, vermin or laundry. He seems to like dressing like a bum, and when he needs clothes, he'll order new ones online. Maybe the pwuNPD in my life is unusual, but I guess I'd sum him up by saying that though he's around 60, he never matured beyond a teen's level. He seems to enjoy living like a college freshman--in dingy, dorm-like quarters, living on junk food, drinking heavily all night, choosing not to work (the adult equivalent of missing classes), ignoring most of the administrative burdens of adulthood (car registration, health insurance, utilities payments, doctor's appointments, etc.), being constantly late to pay bills, getting his electricity cut off and scrambling to get it back on, ignorning basic home maintenance (fixing the roof), etc. To continue with the dorm analogy, I understand from his kids that he vomited in his home but never picked it up, and instead he threw cat litter on top. And that's generally how I think of him these days: his behavior, social-emotional skills and functioning generally resemble that of certain 18-year-old boys. It's just that in a 60-year-old body, his behavior seems incredibly dysfunctional, and his body has deteriorated after decades of ill treatment (junk food, heavy drinking, untreated high blood pressure, untreated diabetes, untreated gout, zero exercise). His could be an extreme case, I understand that.
