It is terribly sad and frustrating that BPD tends to be a lifelong condition and while peace can be had for moments at a time, it seems some underlying trigger always elicits the problematic behavior at some point.
There’s a lot to grieve here. That you will never have a mutually satisfying relationship that could be available with an emotionally healthy partner is tragic. But it is what it is and you’ve chosen to continue.
It seems you’re doing all the things that are recommended for having your own healthy relationship: outside interests, hobbies, activities, some friends.
I’ve learned to detach emotionally from my partner, which sounds callous and self focused, but I let myself enjoy the times when he’s a positive influence to be around, and avoid him when he’s emotionally draining. It would be nice if I could wave a magic wand and heal him from all his childhood trauma, of which there is granted, a lot!
However I have my own childhood trauma and that is where I seek to heal myself. One thing I’ve learned is that from a young age I was *trained* to be a people pleaser and take responsibility for other’s emotions. I’m leaning not to do that anymore.
