Left my wife a month ago but going back to help with her mental breakdown

Hi all.
I left my wife about a month ago, I already posted on here about it.
Anyway finally told her I was leaving and we could talk about division of assets in the near future.
To make things easy on her I said we would not do anything with all the assets for another year and we would split profits and wages from the company 50/50.
I can honestly say I am much happier in my beautiful but small apartment, I can feel a sense of my real self coming back.
So during this break up my wife has had a mental breakdown and is seeing a clinical physiatrist along with acounselor , so about 3 appointments a week.
She has been begging weeping , losing tons of weight and she was already super slim, for me to come back.
So I am returning home but will live in the pool house .
She thinks it will be easy on her if we can disengage over time with me still living on the property.
I really would prefer to be left alone but I see her everyday in our family business.
I’m losing a ton of money giving up my 1 year lease 11 months early.
I fear she will go top herself if I’m not around.
What to do ?
I’m feeling pretty down about returning and living next to her

I recall having read one of your previous posts on this topic. Honestly, I wouldn't know what to suggest to you with regard to this. (Perhaps other PC members will have some thoughts they can share.) My personal opinion is this is a complicated enough situation that it is something best talked through at-length & in-depth with a mental health therapist. If you're not currently seeing one, perhaps now is the time to find one? My best wishes to you...
