Hi Mabi,

It sounds like you are way down... .and that's a familiar story you will see here if you take some time and read the posts of other members. Having a loved one suffer from traits of BPD is very mentally, emotionally and physically draining. We know... .many here either are there, or have been there! You are not alone.
I'll ask straight forward... .your subject reads 23 years in hell... .What do YOU want to do here? Are you looking to save your relationship? If so, there are plenty of tools and lessons here that can help you on your way, as well as member input from their own experiences. I ask, because your post isn't clear to me what YOU are looking for here.
I will say... .either way... .your immediate situation calls for some understanding on your part. Most of us here get that we cannot change our person with BPD, but we can change how we react to and communicate with them. Combining a working understanding of the illness and its nuances with some self centering and using the communication skills suggested here can help improve your situation. To the right margin of this page you will see some tools and lessons to help guide you into implementing these very things.
You've found the right place for knowledge, understanding and sharing. Feel free to share any questions, thoughts or feelings. We are here.
