Hi Geo,
A big Aussie welcome to Susan's family. Good to see you are doing the right things about talking to your wife and seeing a therapist. A very balanced way to approach the matter.
All strength to you if you can live that way, just waiting. Your wife may be interested in joining you here in the Significant Others section. I'm sure she would get some relief and possible answers there.
Look forward to hearing more from you in the coming time, but in the meantime, be safe, well and happy.
Lotsa huggs
Catherine
