Hi Supersad,
Welcome and hello

Thanks for telling us a little about what brings you here. It can be hard to define the difference between bipolar and BPD, and they can even both exist together. What kind of treatment is he receiving? Medication? Therapy?
That must hurt to hear him say he hates you every day :'( Is it always hateful, or does he ever have periods of tenderness?
How old is your child? What kind of arrangement do you to raise your child together?
I'm glad you found the site and hope you let us know how you're doing.
