Hello anatexis,
Welcome to bpdfamily.
I am sorry for the hurt you are experiencing and the troubles in your relationship. I can certainly and vividly relate to what you describe. My story isn't much different than yours. Actually it's pretty much the same, I once fell asleep in the middle of a conversation with my partner because it was 11pm and I was tired and she woke me up to throw me out of 'her' apartment because I was being 'mean to her.'
Over on the right hand side of the screen are a bunch of helpful links. This is a cut and paste from one of them.
Have an emotionally difficult person in your life? Are you blamed or criticized for most everything wrong in the relationship-even when it makes no logical sense? Are you the focus of rages and alternating periods when the other person acts hateful or very loving. Could it be BPD?
And here is the link.
https://bpdfamily.com/tools/articles2.htmI used to be bewildered too at the weird things we used to fight about and how rapidly things could change on a dime. Since I have been coming here I have learned what BPD is. I have come to understand how my partner processes information and the world around her. I have learned communication skills and tools. And we no longer have those weird fights. Now mind you sometimes we get close to having one but we both can pull back before it escalates into something larger.
Have you heard from her today? When she texted you that she needed help about three months ago did she end up pursuing that? Did she find a therapist?
How are you feeling? I think it's a great step coming here and posting. It's a great way to get support for you. We all get it. We all have had those same experiences that you just described of it being all our fault. Keep coming back and reading and posting. Our shared experiences help us all.
Others will be along to say hi. Until they do be sure to take a look at that right hand column.
