Note that your friend's 3rd house of communications and thoughts is exactly at 29 Aries, which is the degree of the nodes, so there is some extra unforeseeable development going on there.
As you mentioned, sun as co-significator of the male, approaches mercury in retrograde, which means repassing over its previous position. Rethinking.
Mercury rules both your friend' 5th of love affairs, and her 8th of sexual relationships.
North node, the point of force, and the sun/mercury conjunction all take place in her 6th house, so you could almost say she has been "sick" over the breakup. It is also his 12th, so he has no idea of this.
She seems to be regretting the breakup, and would like to see him back with her.
