Does divorce occur with the statement, "I wish that from this week until you travel, you would stay in your house, you and my daughter, and you would not go to your family's house at all," with the intention of prohibition, not divorce? And does it occur again upon her going to her family's house after returning from travel?

The apparent meaning of the phrase "تَلْزَمِي نَفْسَكِ" (you are bound to yourself) is one of the allusions to divorce, because it means "do not bind me." And since this wording is an allusion, as long as the speaker is not certain that he intended divorce by it, then no divorce occurs. Similarly, nothing is entailed by mistakenly writing the word "ما اتروحيش" (don't go); the determining factor is the intention.
