Hi RippedTorn
I'm not sure about the RO. You're probably better served asking your attorney about that.
Regarding the emotional age of your partner as a reason for her not wanting to leave, it's not easy to guess what the partner's true reason for an action is. Often when thinking about whys, what can help is accepting that there often isn't one consistent answer, so it may not be very productive to look in this area.
I understand a little about the mental detachment, but without spatial detachment. Sometimes even when partners live away from each other, seeing each other in the same space can cause us to react mentally. If this happens at home, it might help to have a quiet place that only you can be in. In this space, you can re-detach mentally. Does that makes sense?
Or, if you have a quiet (safe) part of the neighbourhood nearby, you can consider that as well. I do think that this process will get easier for you over time.
I don't know how able you are to talk to your wife, but if you're both able to have productive communications, you can look at arranging your own spaces and timings so both of you are able to get that mental separation. I hope that helps.
