Hi all, sorry if this is not the right place to post this. I see you have a flair for family members but I've never really seen a post... I also can't multi-flair this, **but there are substance abuse and suicide trigger warnings within as well.**

&amp;#x200B;

My (24m) mother (48) was diagnosed with BPD along with a handful of other disorders (PTSD, Bipolar and more) two and a half years ago.

&amp;#x200B;

Prior to this, my mother has gone through a number of challenges in her life, where we were all by her side.

She has always been varying suicidal, and has made a number of attempts on her life.

She had a serious alcohol addiction running many years. She drove drunk regularly, got into at least one car accident, and was neglectful in her care of my siblings and I (8-14 years old at the time).

She was never particularly a caring or loving person. Not towards us or our father.

But she was our mother. She would occasionally throw a fit, disappear for a day or two to another property we owned closeby and tell us to stay away, but this was all stuff that we were used to.

&amp;#x200B;

The turning point with my mother was when she started at Alcoholics Anonymous. Eventually she stopped drinking, and started seeing psychiatrists. She was diagnosed with the above disorders after a stay in the psych ward, she had driven herself in because she felt strongly suicidal.

&amp;#x200B;

Then she started more regular fits, saying she was going to divorce my father. She never did end up divorcing him, but would regularly swing between being happy and wanting a divorce. Eventually, she cheated on my father. He told her to leave the house, and that he would help her find an apartment to stay in while he figured out what he wanted to do.

She left and moved in with one of the 2-3 guys she had cheated on my father with. The moment my father found out, he started the divorce process.

The divorce was needlessly drawn out, my father says it was my mother. And after the divorce, my mother is a very different person.

&amp;#x200B;

She has systematically tried to break communications with each of her children, but won't commit to it. One day she will send us something incredibly rude, the next day ask us how school or work was. All three of us have since gone no contact until things start improving.

Every day she posts 10-20 posts on Facebook. Varying from disparaging my father, to how she's very happy with her life, to how she's thrown out the trash, to how her kids are angels, to how her kids are "assholes", "disrespectful", "mistakes".

She was engaged to her boyfriend within 8 months of moving in with him.

She is disputing my father's annulment with claims of 'sexual harassment' by encouraging threesomes.

She's regularly calling my father's parents with these same claims.

&amp;#x200B;

When we have confronted her about what she's doing to our father being hard for us as well, she has told us to keep our noses out of her and dads business.

As a final note, the breaking point for myself was when she had asked my sister to be her maid of honour, for her boyfriend who my sister has still refused to meet after 10 months at the time, on Christmas Eve.

&amp;#x200B;

So, for those of you who have a better understanding of whats going on, is this my new mother, or has this been a two year long episode? Is there any additional perspective you can offer?

Thanks.
