Hi sadboi and Welcome!
I've read your posts and can see that it's good you found us. Many in this community will relate to the experiences you've had, as can I in many respects. Particularly around the self harm and suicide attempts. These are extremely difficult to deal with on an emotional level and take so much of your energy and thoughts up. I feel for you for having gone through this with someone that you love. I can remember feeling like I had nothing left over for any other part of my life and being about as worn down and traumatised as I can remember by the things I saw and heard. These experiences can keep us in a state of red alert, which is very draining emotionally.
Huge credit to you for taking your own well being seriously and getting the support of a T. Recognising your codependent traits is a great step towards reclaiming your responses and fostering healthy decision making processes which include consideration for your own needs.
I miss her, I love her, I want her back. I've had a couple bad moments of really emotional text messages/phone calls, but I can tell she doesn't miss me as much, especially because she is in a new relationship. I have since started to see a therapist and am working on my codependency issues.
If I do not contact her again and continue working on myself, is it likely that when her current relationship ends she will come back to me?
Breakups are painful and none more so than a BPD r/s which is intense and intoxicating from the outset. The idealisation stage sells us a fantasy that is hard to break free from once we're invested in it. She is currently in this stage of a new r/s and that is hard to think about, I know. I've been there. Hang in there, it gets easier. How long has it been since you split up and are you still in contact now following the calls and texts you speak of?
For myself the thing that allowed me to truly begin to heal was to take some time and space to turn my attention fully onto my own needs. This was difficult as a codependent however very worth the effort. Try to see your working on yourself as something you are doing for you, rather than for someone else. That is a step towards valuing and loving yourself more, and we could all use some of that. We cannot control whether our ex partners decide to come back into our lives, only how we proceed for ourselves and how this time is used. See it as a new beginning. If she comes back to you, you can potentially be emotionally healthier and living a full and satisfying life. Nothing wrong with that! The journey to healing is a marathon, not a race though so take it one day at a time and be kind to yourself. Expect to be hurt right now. That's natural.
I know you've done lots of reading about BPD. I'd also encourage you to do some further reading for your own benefit and hopefully increase the knowledge you have about your ex and her behaviours. It can help to de personalise what you've experienced with the discard. A great place to start is with the lessons to the right of the board and I personally found the articles in the self help materials above these to be extremely valuable in how I perceived things.
One of the first to help me with this is the following:

It gave me insights into what happened and very much like you mentioned in another post, also saddened me to see that our r/s was not so 'unique' as I'd imagined. Still, it did allow me to gather my thoughts and consider my stance on things. I hope it's helpful to you too.
Love and light x
