You are taking this all in stride and are doing so well! It is going to take time and effort! for him to earn your trust back. Hopefully he will do the work he needs to. Are you prepared to set up those boundaries and ask for things like transparency as SA mentioned?
For me, since my trust in my H has been broken, I can't imagine ever trusting him the way I did our whole marriage up until the MLC. Scary to think about, but I guess with time and effort it can slowly come back.
