My partner and I have been in love for a long time, ridiculously so. She has Dis-associative Identity Disorder and has been switching into alters through the course of our relationship.
She was so very much in love with me until a few days ago when she woke up and decided to break up with me. (I mean, like, nobody else in the world mattered to her, she was talking about how we were going to grow old together and kissing my toes and belly type thing)
Now, normally I would accept this.
But she's so cold and so unlike herself. She's acting irrationally, saying she's going to join the airforce and that I'm responsible for holding her back in life. I am a transgender man and she's always loved that but when she woke up she told me all she wants is a penis inside of her and that I'll never be enough. She's cold and snappy, calculating and mean.
But at night, when I ask to sleep beside her (currently still living with her it's been a week) she gladly accepts cuddles and a few nights ago told me she loved me in her sleep.
WHAT THE ###$ IS HAPPENING?
The personality change is TOO DRASTIC. She went to Cali a couple of weeks ago, the place where she was molested and her grandpa died a few days ago. All she could say was "My grandpa died

When she found out her grandpa had cancer she cried for days, and now he's dead and all she can say is "The dead don't care if you cry."
This is NOT my little happy wubble, something is so wrong.
I suspected the "Blunted Affect" theory because of her PTSD and DID, but I dunno! She insists this is her and that nothing is wrong but she's literally saying and doing things she would never even imagine in a million years!
She's not taking any meds or getting any help and I dunno what to do, we're so ######6 in love and I want her back damnit. Please help me I'm so desperate! Her moods keeps shifting, she gets angry randomly and then super textbook emotionless the next!
Please help. Please bring my little wubble back to me. We were planning on kids and marriage, and suddenly she hates me.
Edit: Don't tell me to just leave her. We have been so devoted to each other for so long and I WON'T leave her. I've been with her through her alters tormenting me physically and emotionally and I can handle this I just need to know HOW.
