Without wading into the therapeutic too much, is there a way to move your PC, maybe to the bedroom. Or to set your partner up with wireless headphones.
I would say it isn’t so important to put a label on either of you as it is to find a workable solution. So frame your approach in these terms, make a schedule for headphone time, don’t engage in the at home therapy. Other than that, look for somebody who knows both of you better than me or anybody else here. The advice is probably going to be better.
How long have you been together? How long since you moved in together?
I’m sorry about your mom’s illness.
What I’m reading here in this thread is that you haven’t found the right therapist yet. And us jokers on the internet cannot fill that void for you.
We all have to live with bad memories. Regardless of quality if we were to enter a pissing contest to see whose suffering is greatest. You’re not living with yours, they keep you as a pet. I would go so far as saying being an obsessive goodie has not worked for you either. So look for a different therapist. At the very least another channel for you pent up regret. You can of course still be nice to the people around you. But you gotta give yourself a break from trying to outshine your average saint.
