I'd like to try sharing and listening with others the experience of living with a BPD. In my case, my ex who is the mother of my 11 year's old daughter.
You'll find a lot of fellow travelers here who can relate to what you're going through.
How is your daughter doing?
BPD captures a big spectrum. How would you describe your ex's traits?
Co-parenting is tough with someone who has BPD, to make an understatement. Have you found anything is working? What kind of custody schedule do you have in place?
