Thankyou

We have been thru this two times before where she has a bad time and leaves me but then changes her mind , but this time i dont think she will .
I have suggested counciling and basically i have told her i would do anything to help us . She is a person that has always run from her problems and not deal with them .
She will not go to anyone she has admitted to not wanting to try to fix us .
Last time i actually got her to come to a councilor with me but after a few days she hated that idea and wouldnt go again (they person brought up a few past issues in her life that she didnt want to deal with )
I know this girl like know one else i have seen the changes in her and i know in my heart that it is not the real her ( i see the girl i fell in love with for a week or so a month ) .
I dont know what to do , she has decided to leave me because she is not happy but she loves me to death .
I dont think her decision making is the real her but more affected by pmdd if she has it .
i have researched PMDD and everything fits so perfectly into when things changed in our lives and changed in her .
What the hell can i do ?
