I have had a similar situation but since it was my wife who blindsided me I haven’t had as much support. You have to live through the anger… feel it and embrace it! It takes a long time … I am 9 months in and I am still furious. People tell me to let it go and move on. All great advice just not advice I am able to follow at the moment. So be patient and ride the wave… wish I could tell you there was an immediate fix but there isn’t! (PS. I don’t jog either but am considering a dog!)
