hi Hopealwaysyes,
Your post will likely be moved to the other section for those with children with bpd (this section is for Parent, Sibling, or In-law), but I wanted to respond and let you know I hear you.
This is very tough. I hear your pain and fear and it is scary, the domestic violence accusations - they hurt. Besides having a mother with BPD that I have been dealing with for nearly 50 years (my whole life), I recently found out my step daughter is likely BPD'd.
It is heart wrenching, it is life changing, and your life with forever feel ungrounded...I get it. But, I want you to know that you've already taken the important first step, and that is to have hope. You can be stronger than you know, and I feel you will find that strength. Please check in here often where you will find friends who understand your situation.

p.s. my Mom tried to get me arrested and it didn't stick. Just remember that your son and your grandchildren have you, that is pretty cool don't you think?
