Hi Taipan and welcome,
15 years is a long time to deal with up and down, totally unpredictable BPD behaviors; I feel for you
When you get a chance, please read through the material provided on the right side of the page-- "Before you can make anything better, you must stop making it worse", followed by links to The Lessons. I cannot emphasize how important and informative it all is, just unbelievably so.
If you can wrap your brain around the fact that we are the other half of the relationship and that what we do and say and our behaviors contribute to a lot of the fall-out, you'll be well on your way to a better life.
Yes, our partners have issues; it's a given. What's harder to connect to for some odd reason, is that we also have our very own issues and they somehow fit and feed into our partners issues.
Try to keep an open mind and heart while reading and posting and whatever else you do while learning all you can about this very confusing disorder. There will likely be many "Whoa... ." moments and insights.
There is no shame in the part we might have played in this dance with our partners. And if we can keep the blame thermometer turned down low where they are concerned, there very well might be some really great days/years/decades ahead!
There is hope, Taipan
