I must be a 'super' senior because I am still around almost daily. To me it is a touchstone. Having a place where people relate and appreciate your situation is affirming for me. I also like to 'pay-it -forward when I can.
No matter what your stage in the process, there are others around the site to relate, advise and cheer you on.
There is not much in your profile....
So I am not sure where you are at in R-
But I can give you a few areas to address-
Transparency- Trust but verify
Honesty- about anything and everything. Big stuff and small stuff
Empathy- towards the poop sandwich handed over to you to consume bite by bite day by day
Remorse- For their actions and the consequences he brought to the both of you.
Settle in. Its a bumpy ride. And its longer than you want to face right now. SI is, IMO, the best and sharpest tool in your tool belt for R. I would put the knowledge base of the posters here up against any great MC or IC including my own. There are many here who not only relate and understand, but also will give you a nudge when you need it.
