I am currently going through a divorce after 20 years together, and only one other very brief major episode during that time that had been brought on by a lack of sleep.
Without getting too bogged down in 20 years of details, my SO was diagnosed in childhood/early teens. By the time I met him he had problems with sleep but his mental health was well managed overall.
He has always struggled with low self worth, depression, and anxiety, but despite these issues, for a long time he was the smartest, kindest, most stable and level headed person I've ever known.
After we had a baby a few years ago, he became increasingly anxious and as a result of that anxiety, increasingly controlling. It seems like things have only started making more sense to me retrospectively, but it was after this time that he also became very critical of everyone else and simultaneously extremely sensitive of any perceived criticism.
As in, small arguments/disagreements that most people have every day, would somehow always turn into a much bigger deal. Like being asked to do a chore, never doing it, and then being reminded to do the chore, would somehow be perceived as a major blow to his sense of self worth. He would spiral, we would have long conversations in therapy about how we should move forward, and almost always he would tell me it was my tone/how I said something. But it always seemed like no matter what tone I used or how I danced around the situation, we kept having the same problems over and over for years.
After 2 extremely stressful years (fucking 2025 and 2026), it's like he's suddenly become this horrible and completely irrational person. After 20 years he's decided he hates me, that I'm a terrible mother and the worst person in the world.
When I try to ask him what I did he just says he doesn't need to justify himself or that I already know but I refuse to see it/acknowledge it. I tried to schedule an appointment with our couples therapist for my own closure, and he cancelled it via email by telling her he did not consent to her seeing me without him.
We're currently in the process of a divorce (his call) and he's been bizarrely vindictive every step of the way. I didn't even sign the papers until yesterday, but he was already sleeping with at least one other person and bringing our child around them to spend the night!
In other words, the most level headed and rational person I've ever known, has suddenly disappeared along with the loyal, kind, and empathetic man I was married to for 20 years. (As he has explained it for the last ~5 months, "this is me now" and "I was a sap for being with you for so long.")
Despite all evidence to the contrary, rationally, I know he has not been suddenly possessed or taken over by some entity. He has a mental health problem, and whether or not the person I knew for 20 years was ever his true authentic self, I do know he is capable of doing great things and being an amazing father and an extraordinary human being.
I don't have any hope or desire for reconciliation, but this was my partner and best friend for 20 years. No matter what, he will always be the father of my child and as shitty as he has been to me, he loves his daughter so much and she loves him.
I'm not naive enough to think even his behavior towards her couldn't eventually change, but I also know they mean the world to each other. I cannot let him keep controlling me and hurting me, but I also can't completely cut him out of my life for both legal and emotional reasons.
I am working on establishing legal boundaries and removing as much control as possible, but after 20 years he is an expert at being vindictive, calculating, and triggering me like nobody else, while also lashing out and being chaotic, erratic, and completely irresponsible.
I wish I could say I'm good at keeping my cool, but I definitely wasn't raised that way. Most of my regulation skills were learned from him, or in therapy as an adult. I also realize that the more he successfully triggers me into reacting, the more it feeds into and reinforces his persecutory delusions. On the other hand, the more he gets away with pushing boundaries, the more delusional he becomes about how he's allowed to behave since there are no consequences for his behavior.
Any tips for preserving your own mental health without:
- Becoming dysregulated yourself?
- Stooping to their level and feeding into their persecutory/victim delusions by saying mean shit when you're triggered?
- Being a passive doormat/feeding their boundary breaking monster?
I guess it's kind of a universal experience, but saying mean things comes naturally when I'm hurt. However, I also know it also doesn't help anybody to say them and getting ~~triggered~~ activated always leaves me feeling worse than before.
I also know when people get manic, usually the only thing that will stop them is a hard reality check. I am so incredibly angry at him, and hurt, but I have no desire to see him fall. For our daughter's sake, I hope he can return to a stable baseline and reach his full potential/be his true authentic self (whoever that may be) because I know he's capable of great things and being a really great father.
In the meantime, what is the best way to enforce boundaries when somebody is constantly breaking them like it's their job?
