NPD & BPD breakup. what would you do in this case?

[Beware of Junk Psychology...]

Dated 2 1/2 years and broke up two weeks ago. She kept liking everything on Facebook I posted. Went on match.com and went on date yesterday, then changed her profile and cover page with the guy. Then called wanting to remain friends AND still date. In her photo, she was wearing hat I gave her and doing a recreation that I cherish that she never did. Flyfishing. I told her I thought it was mean and uncalled for and she said it was her life and if I didn't like it, Unfriend her. So I did. She then got really mad and said to never call her again.i told her I would not, but that she needed to understand how asking me to be a friend and date, and doing this was hurtful and intended to cause pain. She is a diagnosed narcassist and does lack empathy, and her only come back was to I was wrong for not being excited for her catching a fish! ! I told her I didn't want to heat from her unless it was a face to face apology and explained that doing the Facebook thing like this was sociopathic and lacked courtesy and class. She said f off. She is 50 years old and behaving this way. So, dump her forever? Go NC? Forget her and never speak to her again?

Do what is best for you mate. 

Do you want to live with someone you don't trust, has no respect for you and gets power when she abuses you? 

If their are no kids involved, smile be happy for her while you sell the house and plan a one way trip out of luniland. 

If their are kids involved then argh :s

That, right there, plus the fact that you're on this site, is reason enough to go NC and never speak to her again.  In her extinction burst, she will probably try to reel you back in and may even offer a seemingly-sincere apology, but the disorder always wins in the end.

2 1/2 years is a long time, and I'm sorry you have to go through this.  I don't know your back story, but I'm guessing it's likely long past time for you to cut your losses.  NC can help create the space you need to heal and move forward.
