The thing is I haven't been allowing it in my life. I haven't responded or reacted to anything. So why can't I just be allowed to move on in peace? What an awful experience. You're not wanted... . unless they suddenly need you for something.
The only way you can do that is by removing her from all points in your life. Delete, delete, delete - block if you can. You see so long as you're allowing access via social media you are allowing it in your life. Remember that you get sent FRIEND requests. For her thats as good as saying that things are okay and you want to continue contact. One of the biggest insults my BPD had was when we would have arguments and I would delete her and block her to get a bit of space. Any time you do anything 'permanent' (as blocking and deleting is) it p*sses them off big time, because you are actually saying "you're not wanted in my life". Some people say that they like it cos it sees that its getting to you, but I totally disagree. Delete her on everything, just do it. Think of it like this, if she wanted rid of you she would block and delete you without a second thought. In fact, the same day as the "bye bye, we're friends, look after yourself x" text, I was blocked.
Another thing you can do is get her to delete and block you - do this, send her a message telling her "NEVER CONTACT ME AGAIN, YOU'RE AN EVIL, SELF CENTERED NARCISSIST, I DESPISE WHAT YOU DO TO PEOPLE AND I FEEL FOR YOUR NEXT VICTIM. YOU WILL NEVER GET VALIDATION, OR APPRECIATION OR EVEN A NICE WORD FROM ME AGAIN, YOU'RE A CREEP, GO AWAY, I MEAN IT, NEVER CONTACT ME AGAIN!"
Words to that effect did that for me, I kinda regret sending it in my dark days - I did apologise for sending it. But that will kill it for you if you're desperate to get some peace. It will end it because 1 - it risks exposure 2 - it implies she has other guys on the side 3 - it exposes her methodology (next victim) 4- it shatters her ego by calling her a creep 5- it pushes the blame her way (never contact ME again).
You honestly are not doing no contact properly.
