Need some positive advice to start again

[janaus]

I know no one here will agree with me. But I decided to stay and try to make it work after hubby had a 3 x fling. You probably remember the story.
On Tuesday he finally admitted after me questioning him and checking his phone and the phone bills for the past 6 weeks.

Well, I only need positive advice please.
So far I am not really doing well. Avoiding being home with him, come home late and go straight to the spare room. So, not cooking or eating dinner. I see him at work but only need to talk about work related things.
How do I get back to a normal routine.
My thoughts are going crazy, imagining things that happened.
Plus the fling started with a customer, after meeting with her many times, her changing her mind on what she wanted for her job, she finally made a move on him and he didn't say no. A mistake he says. No, it was a choice.
I am angry, hurt, feel betrayed, being blamed, sad at loss.
Dr. Told me to write my thoughts down. So I've been doing it.
Yesterday I wrote a page of positives, happy memories, good family times, great holidays. But today I am struggling to be positive.

What does the 'normal routine' that you want to know how to get back to consist of?

I don't 'remember the story', but if you have a thread you created earlier on this board you're probably best advised to update it with the post you've made here so that responders can be made aware of the backstory, and so that you can use it as a way of charting your progress from discovery to your current feelings and forward to the eventual outcome.
