What is the ruling on the phrases "If I decide, I will make her lose, or I will put her out a loser" and "Then the son will be with me," without intending divorce by them, and are they considered a divorce?

The phrases mentioned do not explicitly state divorce. If he did not intend divorce by them, then it does not occur, and nothing is binding upon the questioner. It is advised to turn away from obsessive thoughts and not to dwell on them.
