She really thinks relationships are all about instinct and just doing what feels right. (Obviously, this is a pretty immature outlook.)
That is a freeloaders mentality. She only wants to do what comes naturally and is not willing to do any thing to maintain the marriage. That is like freeloading in a house and doing nothing to maintain the house. Pretty soon the house falls apart. check out the book, Buyers, Renters, and Freeloaders by Willard Harley:
Freeloader is unwilling to put much effort into the care of his or her partner in a romantic relationship. He or she does only what comes naturally and expects only what comes naturally. It's like a person who tries to live in a house without paying rent or doing anything to improve it unless the person is in the mood to do so.
Renter is willing to provide limited care as long as it's in his or her best interest. The romantic relationship is considered tentative, so the care is viewed as short-term. It's like a person who rents a house and is willing to stay as long as the conditions seem fair, or until he or she finds something better. The person is willing to pay reasonable rent and keep the house clean but is not willing to make repairs or improvements. It's the landlord's job to keep the place attractive enough for the renter to stay and continue paying rent.
Buyer is willing to demonstrate an extraordinary sense of care by making permanent changes in his or her own behavior and lifestyle to make the romantic relationship mutually fulfilling. Solutions to problems are long-term solutions and must work well for both partners because the romantic relationship is viewed as exclusive and permanent. It's like a person who buys a house for life with a willingness to make repairs that accomodate changing needs, painting the walls, installing new carper, replacing the roof, and even doinf some remodeling so that it can be comfortable and useful.
My wife is afraid that both of us will never be able to get over the affair (my anger and pain; her guilt). She also says she feels enormous pressure for us to succeed at reconciling.
She is probably correct given her reluctance to do anything to get over the affair. Do nothing, avail nothing. Its real simple. Hers is a self fulfilling prophecy. If she doesn't make changes,ie: affair proof the marriage and commit herself to CARING for you, y'all WON'T get over it. You can't grow a garden unless you plant some seeds and grab a hoe. Gardens don't happen by magic and neither do good marriages.
I would let her read this article about forgiveness and what it will take to gain your forgiveness. In order to recover your marriage, there needs to be JUST COMPENSATION:
