I’ve had nearly an identical experience: married at 23, never lived alone, got my first apartment at the end of a 28 year marriage at age 56, found out I liked being "by myself” as I like to say instead of “alone” and three years later in a house of my own by myself and loving it. My music, my decor, no decisions by committee regarding meals, decorating or anything. I like going naked when I want, too. I’m also thinking I’m becoming a hermit and may never consider living with anyone again. The terms of the divorce also make that a bad move from a financial perspective. I’m glad you like your life now.
