I am currently facing an extremely draining dynamic in my relationship, and I’m looking for honest perspectives.
The Context:
My partner and I have been through a lot. To be clear: I didn't cheat on her in the traditional sense. I was under extreme pressure in the relationship, and I broke. I distanced myself, and in the aftermath of our separation, I turned to the first girl I found in my path. When she came back and demanded another chance, I tried to treat her the same way she used to treat me—coldly, with the same harshness she once showed me. But she couldn't take it. She broke down crying, and I felt the weight of it. I softened, I apologized, and we fell back into the relationship. Months later, the story shifted: she started using my own tactics against me. She struggles with BPD ، which manifests in extreme 'splitting' (idealizing me one moment, devaluing the next). I need to be honest: I haven't been a passive participant. I've deliberately used manipulation—intermittent reinforcement, gaslighting, strategic silence, and graduated tests of obedience—to reshape her behavior and make her dependent on me. I even fabricated having DID , so I could mirror her “two sides” and feel a sense of control. I recognize these as deeply toxic patterns. I've become someone who plans, studies reactions, and measures results, and I feel a twisted sense of safety when she submits.
The Current Situation:
Every disagreement feels like a war. She uses 'reposts' on social media to express her pain and anger, which I usually interpret as a test or an attempt to provoke me. Whenever I stay silent or try to set boundaries to protect my own mental health, she interprets it as abandonment, which triggers her deepest fear of being left alone—especially at night. Our entire relationship is built on a symbolic language we created out of crisis: I'm her “light,” she's in a “pit” without me; her pain is a “thorn” I'm supposed to remove; sexual photos became “evidence” of her trust, and physical touch became a way to mark ownership. I've let physical intimacy become another method of control, and I've pushed limits until she gave in completely. What's changed now is that she's learned my weapons. She now wields silence, withdrawal, and provocation—the very things I taught her—and it's tearing us both apart.
My Struggle:
I truly love her, in a way that is possessive and distorted, and I have taken on the role of her 'sanctuary'—the one who stays, who listens, and who tries to de-escalate her outbursts. But I'm starting to see the cost. I'm losing myself in this. I suffer from chronic insomnia because my mind is always strategizing, always calculating the next move. I even sabotaged my own academic path to buy more time for this relationship. I know I'm causing her psychological harm, and I'm terrified I'll push her past a breaking point where I lose her for good. I don't want to destroy the person I love, but I also don't know if what I'm doing is a disorder or a destructive cycle I can't escape. I'm asking myself: where is the line before she breaks—and before I break myself?
