Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Unless her core personality/emotional/boundary issues are taken care of via lots of counseling and hard personal reflection then there will be no underlying change and she won't be safe. She didn't do this last time with the ex, but hopefully she will this time with you if she really is being authentic going forward.
In terms of being open with all accounts, phones, and whereabouts it is more about her resistance or compliance with it that will give you a vibe of if she wants to hide things. As Betrayed noted, cheater=adept liar. Shevery well could just keep it better hidden in the future with this guy or another and you could be fooled again.
I agree with putting your ducks in a row again. I have a post-nup put in place that protects my assets in the case she is just pretending to be repentant. Again there are legal loopholes with this but she didn't think twice about signing it and told me she was dedicated to me now and would never do this again.
Your earlier post noted that the new guy promised more financial security and she wanted it. I worry that she just looks at guys as a means to an end rather than a person with worth/feelings. I hope that I am wrong and she isn't just staying with you for security/familiarity till the next opportunity.
I only tell you these things in hopes you can prepare yourself for the good fight. Go to therapy for yourself as it is the best avenue to vent and express your feeling. You may find yourself tempted to vent to family and friends but they will choose sides and relationships will be impacted. A good therapist will help open you to different perspectives that the fresh pain of betrayal will naturally make you resistant to on your own.
I also recommend marriage counseling. You will be exposing yourself to additional pain at first, but it is critical that your life together is built on a foundation of trust and equal individual investment in the marriage. Her natural inclination will be to put this behind you both as quickly as possible and forget it happened. You cannot do that if you want to find trust and security in the relationship, again. This is going to be very hard for both of you, and you need to go in with eyes wide open and hearts absolutely committed.
You are both in my prayers.
Your wife can't fix the infidelity, in three neat weeks, like you describe. Infidelity is a complex creature that shatters a multitude of emotions, beliefs and trusts. It cannot be repaired by the perpetrator alone, and not in a short period of time. She did it, but she can't fix it, nor can she fix you. The only thing she can fix is the behaviour within herself that causes it.
The extent of the damage she's caused you, hasn't even hit you yet, and probably won't for a little while. You're in crisis control mode; you're raw and scrambling to batten down the hatches after the storm has already hit. Your world map has been ripped out from under you and she can see your pain. She is saying and doing all the things she knows you need to hear and see. It's time to tune her off, and start listening to the station that's playing the voices in your head, without the cacophony of her mollycoddling.
You may want to seek therapy to unlock some things you can't figure out on your own; likewise for her. If she acts and talks like she has all the answers, I doubt its authenticity being that she recommitted in a new relationship.
The process of discovering yourselves, why it happened, your true feelings around it, and what it will take for a successful reconciliation can take months and longer before you feel content in making a decision. You may feel yes today, but all it takes is one trigger and a poor response from her, and you'll be back to square one.
I sense an urgency in your postings for things to get back to normal, and this could hinder your progress and reconciliation. At three weeks in, neither of you are in a position to know if your marriage will work. You're in the grief period, and haven't had an adequate amount of time to digest what all happened and how to process your emotions over it in a healthy way. You may be surprised to know that it can take a number of years before a marriage recovers from infidelity and that's only when it's done in a healthy and mutually respectful manner. There are a number of books and online resources that breakdown the processes of recovery for a betrayed spouse after infidelity.
Wishing you well.
