Not completely caught up with you sitch but I've been reading most the recent posts here and there. It's rough knowing they love you still, but the sad truth is love doesn't keep M's together forever. My W won't say it to me but I hear it from others. Even if they do love us, they aren't showing signs they want to work on the M so we keep doing what we need to do for ourselves.
My W lately is keeping small talk also about work, not exactly sure why but it can be frustrating. Try not to gain too many expectations about her speaking with you. It's unlikely she's speaking to you for a reason you think,but it is possible down the road it could lead to her softening,just don't expect it now.
Accept what is, let go of what was, and have faith in what will be
