See, the problem is that this kind of admittance destroys the foundations upon which your marriage was built. You realize that there is something rotten inside and it's nearly impossible to remove completely. Forget respect, you will question everything about the two of you. Most important thing here is that she has to understand that she will have to work long and hard to regain both your trust and respect again. You yourself need space to process what she said and what your position in that story is. She might find your bond to be stronger than it was before, but you'll find that your bond is far weaker than you thought it to be. Whichever the case, you have the utmost control here and your decision is final.
