Does a divorce occur if the husband said to his wife during an argument: "If you travel, you are divorced," then they reconciled and traveled together, knowing that the husband meant her traveling alone?

If the husband intended, by conditioning the divorce on his wife's travel, that she travels alone, then the divorce does not occur if she travels with him. This is because the determining factor in an oath is the intention of the one who swears it, and intention particularizes the general.
