Don't worry about giving details, it isn't gossip, but it gives us more information as to how to interpret what we see in the chart.
So you are mars, in its fall, so as you say, in a weak position, and in the 9th of foreign lands, so far from him.
Moon, which shows us what you were thinking, is in the 3rd house of communications, which is the problem, and moon is in detriment so also weak. Two problems.
He is Venus, in a better position by being in its own sign and its own natural house. And mercury has recently passed over Venus. As Ilene wrote, this could be a younger person he was involved with, especially since mercury also rules his 5th. However, with the new info you gave us, mercury also rules his 2nd of finances, so this could also be the problem he has at the moment.
His 3rd of communication is moon, who we have seen is weak, and he has weak mars in his 3rd, so he's been having difficulty communicating and been irritated.
What we do see, however, and which is very positive, is moon from your 3rd approaching him, Venus in his 7th by trine, very promising. So by you reaching out to him and communicating you can get on his good side and reconcile.
Notice that on his cusp is disruptive Uranus, the planet that divides and wants freedom and space, which is what he has expressed. And sun, his ego, just passed over Uranus, making this urge very strong in him.
There is also Saturn by the cusp. of the 4th of endings, which is what you are thinking about.
So, where are you headed? Mars will square Chiron, the wounded healer that teaches us llessons. It will be a hard lesson for you, coming from a square.
At 5 cancer you are in the Face of Venus, showing good feelings for him.
Is that enough?
You will also trine that separative Uranus on the 7th cusp, which is your cusp of relationships as well as his ascendent. You might need some free time too. To consider what has happened between you, to regain your strength and be ready for when mars trines Neptune of romanticism and spiritual true in your 5th of love.
This chart says there is a difficult period, but don't close the door just yet.
