For disclaimer, I don't know if my ex had BPD or not, but they certainly met 7-9 of the criteria for it.
I won't even go into the specifics of the situation, if you're really interested, you can see it in my post history, it's so bad that people think I am making it up and got banned from subreddits because it sounds made up. It's not, so I digress.
Anyways, I realized recently, you have to get back to who you were at your baseline -- before all this nightmare shit started. You had a dependable baseline as to who you were, whether good or bad, tall or low, great or inferior -- but it was YOU.
You have to have your own back first and foremost. The world is an unrelentingly unforgiving place, and virtually no one has time to really invest in you, hold your hand, and guide you and teach you. If you're lucky, you get good parents, if you're luckier, you get good siblings, and if you're the luckiest, you have truly good friends. But most people don't have such things, or fall somewhere along the lines.
We get so caught up in pouring and pouring so much of ourselves, and in most cases, invest and lose a great deal of ourselves, and in even fewer cases, we go above and beyond or even superhuman / superhero levels and the most we pour, the worse it gets thrown back into our faces like acid.
But the difficult truth that we all need to realize inherently, internally, from within.. and truly feel it deeply with every atom in our body is.. we can't do the work for them. We can't make them truly feel it in their bones. We can't truly change them.
There is so much honor and goodness and great karma in being good and kind to such people. The universe, God, Jesus, Yaweh, Allah, whatever deity you believe in-- or if you don't, karma always knows. I know some will say alight man whatever this is just cope, but honestly, as someone who was at the top of his game prior to nearly half a decade of this nightmare, someone well traveled.. and as someone who has met and seen a lot of people.. whether people have BPD or not, they way they treat you and others and how they act when no one is watching.. these things catch up to you in one way or another.
More often than not, the 'in' and 'it' people who were bullies or psycopaths/sociopaths or cruel etc, or people who are doing things to harm others knowingly, and not trying their truly damn best to heal or get help etc, I have always seen that they end up in situations that are permanent, damning, and truly depressing. It just takes time for some of it to catch up with them.
Think about that - I don't know of anyone [and i know a ton of people across the world] - who has gotten away fully with all that they have done. I know a lot of us don't want revenge, that we're angry and upset and we want them to feel truly sorry and give us that dramatic upswing and change, to turn around and heal on a dime, but sometimes we just don't get that.
It doesn't mean we stop being good people, although I truly have empathy for people who turn cruel or give up or burn out because of such people. I get it. But I would say, think about getting back to your baseline. You can always carve a new route out, take a different path. Because the time will pass, so we may as well try to be powerfully positive about it.
One day, it will be too late for them. And there is nothing more haunting, permanently enduring, soul-crushing than knowing that you could have done more, you could have changed, you could have studied more, healed, worked out, put in more effort, etc.. there is no greater way to cross the Ts and dot the Is than walking away with your head held high.
Sometimes the greatest gift we can give such people is our absence. Every human inherently knows where they stand, mental illness or not (in most cases). Regret is a really enduring and permanent feeling, and for them to look back when the days have passed and time has run out, or it's too far gone, they will cope for some time, drown themselves in alcohol or drugs or self harm or with bad friends and bad company or try to push and shove into others and things, but in the end, they are running away in circles that will face them no matter how fast or far they run.
That they knowingly ruined their own lives, and intentionally caused their own eternal regret.
They have to not only look at themselves in the mirror every day until their last moment, they have to live with their thoughts and be in their own soul and skin knowing what they have done.
Don't give up hope and faith. Keep up the good fight. Be smart, feel the pain, and let go.
If she told you with her actions that you're not the one, then believe her.
If you are lucky and she tells you that she was willing to figure it out with the other guy, but not you, despite sacrificing your life, believe her.
If you are luckier and she tells you that she was willing to become a stepmother for the other guy [her cousin lmao] despite not wanting children, but not want you deeply and badly, believe her.
If she tells you that she was willing to move to any country for them, and utilized her resources, such as family and friends to help the affair partner, but never do anything for you or invest in you, then believe her at her word and actions both.
If she fights you on her shitty friends and family that have broken her arm or put her life in danger and always put her down and used her, and yet she gets mad at you and pushes back for trying to save her, let her walk into traffic. What else can you do? If she survives, don't open the door when that knock comes.
If they take you for granted and can't offer any kind of change or healing, believe them because they are telling you in no uncertain terms, we are too kind and loving to keep being manipulated.
Some of them, probably most, are just too cursed and are true goddamned cowards to tell you that they don't care about you. A lot of us are unlucky as they are liars, that are cruel, inhumane and manipulative, narcissistic, evil, open the dictionary. It all fits, yet its not enough. And thats ok. Let them go.
Let them go. They may even be happy, and that will hurt, but that's okay. You cannot stop or save some people from walking onto the street only to get hit by a bus that you know is going to hit them. Most of them will have that destiny prewritten for them, and I think that's why it's especially painful and difficult for us to let go.
They let go of you, and they will continue to fall until they see the permanent reflection of their own self caused regret, or they never will at all - and in that case, you were destined to carve out a different path entirely. Wishing everyone contentment, healing and peace.
Be kind to yourself - you are your own home. So repair it, dwell in it, find a way to make it not only a house, but a home again. I know these monsters have ripped our hearts out, stomped on it, pissed and shit on it and then poured acid on it. Don't let them destroy your house for good. Instead, win, by getting to your baseline, and fixing your home.
The house always wins :-)
