My mother blamed her children for her lousy marriage, since according to her, we were what she and my father argued about, and but for us they wouldn’t have a problem.
My parents dated, got married, and immediately began having children. Lots of children. If my mother’s words had any traction, you’d expect that once their children were all grown and gone, my parents could resume or begin that supposed good rapport. I don’t think I need to tell you no such thing happened.
