Rev, I can somewhat relate as my W was a SHM for most of the kids younger years, only entering the workforce on a part time basis about 5 years ago. A few mos ago, she received a new job paying double her current salary. I worried that this would lead to W getting her own place and feeling justified to leave me now that should could afford to be on her own.
I don't know what advice to give you, other than I tried to be supportive and encouraging to W. I made sure to ask lots of questions about her new job and I continue to do so when we're together. If nothing else, I think it's made W feel more comfortable around me and is helping build a bridge of communication between the two of us. Remembering and asking about even small troubles or challenges she's having shows that I care about what's going on in her life and is giving her someone to talk to
