Im in the same situation as yourself, something happened between us Friday with then a turbulant saturday and sunday (via txt) where we both then decided to end it and i blocked him. I cast a chart yesterday and got the same chart as you.
The moon/saturn past square is obviously the "no contact". Mars was the culprit here of the cause of things, so the argument would have been ignited from something you said/did ? This is what happened in my case anyway.
Mars is now separating from a quincunx with pluto, this aspect has been the cause of our trouble. I suppose if we do want to get back with them, were lucky mars/pluto were not in opposition.
Quincunx is the irritating aspect, not being able to see eye to eye, can't sympathize with the other person, communication is not free flowing you don't get each other and things can be taken the wrong way, theres a lack of agreement, not being sure if this is what you really want....etc etc.
Now there is the applying sextile to mars from his L3/moon, which would show some communication between you both. The thing is when this happens mars is still in orb of being affected by pluto (mars needs to seperate a bit more), and we know pluto brings power struggles. So when moon sextiles mars, there is still that unease of not knowing what to do.
How the moon/mars played out for me in my chart....i cast the chart at 3.02pm yesterday, so my moon was at 14.55 Libra. So approx 7 degrees away from making the aspect to mars. Well at just past 11pm, i had a weak (alcohol fueled) moment and unblocked him, then msg'd him telling him that it had been a hard day for me dealing with us breaking up and was missing him, and wished it had never happened. He replied his heads been all over the place too and he misses me.
But ive got doubts about getting back with him. So i think your going to be experiencing much the same thing.
