You ask some good but hard questions, Heartbroken. However, keep something in mind. When my BH decided to stay with me, he knew that staying with me meant that he would have to deal with OM the rest of OC's life, that our lives would be complicated, that it wouldn't be easy. He took me back knowing--and ultimately accepting--the new baggage that came with me.
If you decide you want to stay with your H, your M may have a lot more "for worse" right now. And you need to know what went wrong in the first place to make him want to stray. What are you both not doing that would fulfill the other? Work on that! My BH and I had no clue how to love each other fully until after the A (and thanks to Dr. H's precepts). Now we are in love and truly passionate in all areas of our M. Your M needs to get to that point to ensure that your H never lies to you or hurts you again and to help you move past the A.
He may change his mind about OC and someday want weekend visits, though ANY decision would need to be mutually agreed upon. Remember, Dr. Harley says all decisions should be made by mutual agreement. Someday you may have to deal with OW (or have a mediator do it for you) on a regular basis. You cannot know for sure how things will turn out, but can you accept this baggage in your M and still want to be with your H, even if he does someday want relationship with OC? You have to be willing to accept your new life no matter what the future holds, and in doing so I think you'll find yourself able to get over your fears and finally move forward.
In my situation, my BH has taken on the baggage with me, we carry it together, and we're much stronger dealing with it together. The key is for 1.) you to start working on LOVE and intimacy in your M (not living in the past); 2.) your WH must have NO CONTACT with OW--ever; 3.) both of you must be completely open about your feelings; and 4.) eliminate love busters (which bringing up the A is a major love buster).
We're here for you, Heartbroken. And as a former wayward, I know what your H is going through--regret, guilt, self-loathing--but if he truly wants to make you fall in love with him all over again, he will do whatever he has to to make that happen. But you need to reciprocate that for it to work.
God bless, Heartbroken. While I don't know you or your name, I am praying for you.
