Comrade changed his mind

In his opinion, a woman in a civil marriage “does not believe a man and will not believe him.” “She will be left alone with the child if her “comrade” suddenly changes his mind and leaves. She will have to raise the child alone all her life,” he noted. It is interesting that Eduard Rossel's statements completely contradict his own life experience. Rossel got married in the late 50s (not in a church marriage, one might think), lives with his wife all his life, and is now raising his grandchildren. Are his family relationships really unscrupulous?
