My perspective on spouse or so staying around is this... It is 100% up to them. When I transitioned was at the end of the line, she was read to walk out the door based on how unhappy I was. For me it was a nothing to lose thing with a partner and 100% chance of me going away. I talked to a therapist and he was "This will be the most selfish thing you will ever due in your life" He was 100% correct it was all about me and survival.
I was fortuante and my partner stayed and has been supper supportive, from hormone injections, to GCS and going to electrolsys with me.
On the other hand have had aquintances who's relations have gone away. They have told me "Did this for me, feel bad my spouse left, but I needed to do this for me."
In the long run I 100% did this for me, as a side effect I am happy, I am not depressed. I have Friends now and not people who were around because I could help them in one way or another. My children like me now, I was not very pleasant because of self loathing before. My buiness has grown after a quick and short down turn, why? I am no longer angry.
If your spouse goes, try not to go hating oneanother, go as friend or in a neutral manner. You are doing this for you, no one else, it is OK to be selfish about this, just make sure your transition does not become your life and consume every moment of it.
Hoping your journey take you where you need to be.
