Dont worry too much AquariusT. He has Moon in Cancer and they really dont like to leave their family. And most certainly not when he is a Taurus. I believe he will indeed be back because in this last chart you see the Moon (him) going to sextile Mars who is situated in his first house and rules his 4th of home. Is it possible that the row was about financial matters? I can see that his 2nd house is ruled by Mercury and Mercury is in a bad way, conjunct the Sun (his co-ruler) which means he has burned himself financially. Mercury also rules your 5th house, looks like a financial gamble which did not pan out?
Your 2nd house is ruled by Jupiter, strong in Pisces,but also going to oppose SAturn and before that some sort of change will take place. The opposition falls in the 2-8th house axis and maybe a loan which cannot be paid back or something along those lines could also have sparked the row. Are you a big spender?
I do think he will come back when he calms down. I am a Taurus and I know I always calm down eventually. But this is according to the second chart you posted.
The 1st chart looks different even though there as well a money issue is highlighted. Jupiter, you, will oppose Saturn retro soon. Saturn is in the sign of Jupiter's detriment, not so good. In this chart Moon is also your co-significator and it will oppose the Sun-Mercury conjunction in the 5th house of gambling (and children) where your husband is combust. Moon and Saturn are both in term of Mars, so I suppose that you were either angry at him for some reason or, because Mars rules your 5th house and is situated in the 8th or other people's money, you both (first you,Moon, then him, Mercury after going direct) will square this Mars. So again, maybe you need to get a loan in order to cover your losses? I am just grasping here of course, only going by the houses I can see and the planets ruling them.
Here, the end of the matter is Mars in the 8th house which will receive both squares. I dont like that very much. Last aspect of the Moon will be a sextile to Saturn, a malific, so that also does not look too happy, notwithstanding the sextile.
When I look at the end of the marriage house, (4th of the 7th), then Venus rules it and Venus is in a bad house (6th) and in fall. Venus has passed the trine to Saturn (which could show that his love for your has passed.( Venus rules his 5th) and will sextile Uranus, pointing towards a sudden separation.
So all in all, I think he will come back, but not because he wants to save the marriage.
