Does divorce take place by uttering words that imply separation or abandonment in songs, or by saying, "I wish I had never married you," or by describing the marital relationship as "we are still engaged," if divorce was not intended by that?

All the aforementioned words of singing and regret over the marriage, and the husband's saying to his wife, "We are still in the engagement period," are neither explicit divorce nor its allusions, and nothing results from them. The questioner's preoccupation with this is following whispers [of doubt/Satan].
