Hi, Sorry to hear about these struggles you are having. I cannot say one way or another based upon this information, but I am no expert. However, there is clearly a lot of dysfunction. The violence is especially worrisome. Have you read much here on the site? Do you feel that learning about BPD (or BPD traits) gives you some insight into what you are experiencing at home with your partner? Do you feel like these workshops here are something that can help you in your interactions?
Sorry to hear about all of your vacations being ruined. My partner manages to do this as well much of the time. You have these great times, and then they are gone in an instant. Funny thing, his mind works in a way that eventually blocks it all out and mostly forgets, mine does not. I remember all this stuff and it is not easy to pick up and go on afterwards, but I do, somehow. But it is not easy. Once he is calm again I am shellshocked.
I know when I read up on this stuff I get a little thrown off at times because he does not met all or even most of the criteria. These are very broad descriptions, and I think this can vary quite a bit in how it is expressed. Reading stories here, supplementing the broad descriptions of BPD with the life stories presented here, is incredibly informative and insightful. Without this site I would NEVER have encountered anyone at all who understands what it is like to be broken up with hundreds of times by one person, and have any affirmation that this is not "normal", but does have some explanation behind it. That really, really messed up my life, messed with my head, these breakups. It wrecked me for awhile because it was so darn confusing and painful. Thank goodness for the people here who share about this, they have given me so much relief. Perhaps you feel some relief here too?
I have learned here, finally, that while he may not have all or even most of the traits, I do believe he has some of these traits and it is serious nevertheless - whatever we call it. Descriptions of BPD are the only thing I've ever come across that give me any understanding of his extreme black and white thinking, extreme statements, and inability to control his thoughts when he is in a dark phase. (We may never have a definitive diagnosis - healthcare here is too pricey, but now I have more tools and a place to run to [here] when I am scared and alone. And an official diagnosis at this point might upset him more than help currently so I am not pushing for one. After all, I can read and start using these tools now, no waiting.)
These insights help encourage me to change and improve. I can't change him, but I can support him and offer better communication from my side to add stability to our lives. I miss out on the stability and emotional support one would normally get in a relationship, what I hoped for by being with him, but I see this as an illness I am willing to be understanding and supportive about until when/if a day comes that I just can't do it anymore. I hope it will be a long time, but I have to be prepared that this isn't the "forever home/relationship" I dreamed of in life. And that is okay.
Take it all step by step. It can't all be improved in a day but after reading this site I am hopeful that more stability is possible, or at the least I have others to help me not fall apart completely. I hope the best for you as you find your way through all of this!
Given all of this, what do you want to do? Do you feel this information can help you improve things?
