Right now it sounds like she's keeping her distance. It hard to hear, to me it sounds like she has emotionally divorced you. She is comfortable now and just is not yet willing to terminate the family. Reasons for this can be many. Women on average being more emotional than men, without the emotional connection, intimacy is gone.
The conversations you hear over S6, I can understand the pain there. Completely normal and ok. Getting some space for yourself would make things easier for you and she may wonder what youre up to.
I haven't read your whole sitch...hopefully there is no PA or EA occurring. Almost everyone here says...my spouse would never do that. Until they do. Be emotionally as ready as you can for that.
My suggestions: Do what you can to be your best self. Nail 180s hard. I think you mentioned depression in the past, that probably weighed on her heavily. As with my anxiety, it can come across as a burden or weakness when we're expected to be strong and its what she's attracted too. Build emotional strength, physical strength. Set goals, nail them. Get income flowing, if she's thinking of D, it doesnt help to be keeping you afloat. Job market is atrocious however if you have skills, can you get income from helping out those that dont want too much sun...yardwork, mowing, handyman stuff. Read up on validation, immerse in hobbies.
If she's checked out completely, this can take awhile. Its a marathon, not a sprint and you just started the race.
Good luck and enjoy the extra time you have with S6!
