In a revocable divorce, a man can return to his wife in two ways: 1. he says something that means he has re-established the marriage with her; 2. he does something with the intention of returning to her. Having sexual intercourse ascertains this even if he does not have the intention of returning to her. As for kissing and touching with lust, this is problematic, and based on obligatory precaution, if he does not intend to return to her, he must divorce her again.
