Living with someone with untreated or unmanaged BPD was like living under a totalitarian dictatorship. Every moment felt like being trapped in a surveillance state—24/7 supervision, constant monitoring, and extreme control over my actions and words. Any perceived “transgression” wasn’t just a mistake, it was treated like a betrayal of the regime, and I was branded the enemy—an externalized source of all “evil” that had to be punished and “made well.”
Much about the Borderline experience is about perceptions, prejudices, moods and feelings. Facts and reality get overwhelmed and denied.
The triggers for a person with BPD traits can vary. It often can be worsened by perceived childhood traumas but not always.
Having children together can make ending all contact impossible after a failed relationship since there are custody and parenting schedules. That was my story. I was clueless that I was dealing with serious mental dysfunction and hoped having a child would make my then-spouse happy with a new life to share. That backfired big time. As much as children are blessings, it can end the adult relationship sooner.
In my own experience, most people will try to stay "neutral" understanding that there are a lot of bitter exes out there smearing their former partners, and so they will take everything your ex says with a grain of salt; they nod and agree with something the ex says just to avoid taking sides, but in practice they'll stay cordial with you and not engage with the smear campaign. In these situations, it's probably better just to stay quiet and let your ex look like the bitter one.
Time will reveal all, usually. Getting our lives back is a process, not an event, and can be compared to struggling through a long dark tunnel but there's a bright spot ahead to focus upon and life will then get much better.
Don't wrestle in the mud with a pig, as the saying goes, because you'll just get dirty and the pig will enjoy it.
