ok, looking at her chart the first thing that popped out at me is her moon in the 12th house.
Please take everything I say lightly and do some research, cuz im only going off of experience and what I have studied myself.
I am not looking anything up in her chart also, Im just going off the top of my head, just want to help.
With her moon in the 12th house, its the house of seclusion. She hides her emotions, its the pisces house, so again she ll swim away til ready to emerge again. Pisces are indecisive and wishy washy (i hate it-but its the truth), with her sun pisces and moon in pisces house, its a conflicting struggle within herself, she needs to find out why shes doing it also, have you asked her why and what comes over her to bring her to the point she feel she needs to break up?
Also, theres an issue with the mother, some kind of
heavy influence over her? Im not sayin her mother tells her to break up with you, but there is something there, with the mother.
Shes a Scorpio rising, very secretive, and trust me you want her to have some down time, or it ll get ugly. Also, with the moon and her rising I wouldnt be surprised if she grew up seeing domestic violence, and that could be a reason for her break up make up senerio. Its all she knows how to do its what shes learned watching growing up.
Her venus and mercury tell me she needs communication, friends, so even though shes in seclusion, I am sure shes on the phone in her bedroom with all the lights off with maybe just the tv on, that with the moon and rising she has it that way.
Im sorry to say, I dont wana say shes involved in other relationships, but I am pretty sure she has other admirers calling her, and that may confuse her too. I am probably wrong but again its questionable.
GOOD LUCK!
