What you did where you told her that you don’t want this… it made fk all difference to the outcome. Stop beating yourself up about it or wishing you hadn’t.
For whatever reason, she has decided she is done with your relationship and was going to leave no matter what you did or didn’t say. And she’s manipulating you by trying to make it your fault.
At least a thousand times during court battles, lawyer letters, false affidavits, abuse and custody hearings I wondered how I was ever going to get through it. You probably feel overwhelmed like that too when staring divorce proceedings in the face.
Know that it will all be okay eventually. All you have to do is take it a day at a time.
