Hello, and welcome to SI, eternallove.
I think you'll find a lot of great resources here. There is a lot of good information both for BS's and WS's in the upper left hand corner of this page in "The Healing Library".
Within this Wayward Side forum, there is also a very helpful post, called "Things that every WS needs to know". I'd suggest reading through that.
Have you read any books yet? A good one to start with is "How to Help Your Spouse Heal From Your Affair: A Compact Manual for the Unfaithful" by Linda J. MacDonald. Another great book is "NOT 'Just Friends'" by Shirley Glass.
Figuring out why you let your boundaries down, and working to repair that part of yourself is critical, firstly to you, and also to your relationship.
Transparency is a huge must as well, and it sounds like you are doing good in that department.
Best of luck to you. I'm sure others will be along with more advice and suggestions.
