A Moon`s progression through house puts our focus in that life area for some time. And when entering a house, leaving house or changing sign inside of a house it always brings some kind of change it that life area. So in this case of a 7th house, the changes could be in form of ending some of relationships or building new ones, depending on the other aspects you have (natal, transit and progressed). With Saturn squaring your ascendant at the same time some separations are inevitable and a feeling of loneliness and isolation is normal.
