Moon/he applies to a square with you/Moon, except that Moon first aspects Jupiter, ruler of the 12th house. If the square had been unimpeded, it might have suggested a difficult coming back together. But his/Moon's interceding contact with ruler of the 12th house of confinement and hidden matters suggests that activities related to his probation/confinement might get in the way of a possibly difficult and likely short-lived coming together.
I think the most telling about this matter is the reception between you/Saturn and him/Moon. With him/Moon in Aquarius, you/Saturn receive him well because he is in the sign of your/Saturn's dignity.
However, the reverse is not so: he/Moon does not receive you/Saturn well, because you/Saturn are in the sign of his/Moon's fall.
I am sorry to say that the difficult nature of the aspect between your primary significators, and especially the adverse reception that he has for you, do not point to a joyful getting back together. Moon's next aspect, as indication of this question's unfolding, is an opposition which does not bode well.
