I think everyone goes through this, and I am not there, but someday hope to be... but Acorn posted a great post about trust after the A.
She suggested to get the After the Affair book and to go through that if your H would be up for it. It is a good book , I have been reading it myself. I am sure others will be posting to help you, too. I know it takes an incredibly long time to get past this, you have been working so hard to suppress your feelings while you were trying to get your H back and now they are bubbling to the top.
Hang in there!
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
