HI
I am sorry you are here, but I'm glad you found us. Welcome to the last club you ever wanted to join.
Aside from the advice you have gotten already. The best thing I can offer as advice is that you talk to an IC (that is a individual counselor). While your faith will be something you lean on during this time faith based counselors aren't the best for this type of situation. The tendency in faith based counseling is to ignore the trauma and begin to guilt/push you into forgiving.
Forgivness given early on is not real forgiveness or grace. It is usually fake and ends up creating a lot of resentments.
I have to agree that your W needs to experience the full effect of the consequences of her choices. She needs to be 100% transparent on all devices, be accountable for 100% of her time. She needs to get into IC so she can work through the lies she is telling herself right now. Her A was not about you or anything you did or did not do. Every M can be improved, but she had many choices that did not involve going outside of the family. Any answer she gives that puts any blame on the OM or you is not the "real" reason. STD test now and in 6 months are a good idea. Some BS DNA test their kids. Others ask for a polygraph test to solidfy that the know the truth. A written timeline with as much detail as you need is a good idea too. She needs to agree to never talk, text or see him ever again. No contact is for life and is a prerequisite for any talk of reconciliation.
It is very common for a WS to minimize the details and while I can't say for sure if that is the case here, my experience has taught me there is always more than she willingly admitted.
Not matter what she says right now, it was a choice she made. Heck it was the same choice made several times. It is 100% on her. Until she shows that through words that match her actions don't believe her words or her crocodile years. She is crying for herself, not the dysfunction she brought to your family.
Remorse takes time to set in.
The general rule of thumb is to take your time and research all of diretions you can go. Doing nothing is still a choice BTW. Not recommended, but I think you understand.
Lastly, I know it feels like your life is rife is ruined right now. It just means it might look different that you expected it to be. Realize that many times during your life you have had to envision a different future.
You will laugh, smile and enjoy life again. This horrible time in your life will become a badge of honor that you wear proudly. It tested you and you came out on the other side.
I suggest IC for both of you. I also suggest meeting with your MD. You would not be the first BS that needed medical intervention to be able to function through this very dramatic time.
Me, I am almost 7 years out from my Dday and I am happy with my life and myself. I reconciled with my W, but it took a lot of work on her part to earn that. I think about the A now, but it doesn't sting nearly as bad.
Keep reading and posting. Educate yourself about your options. Read about infidelity. See an IC to help you process your thoughts and help finalize what direction you want to take that is best for you. I know that sounds selfish, but it is the only way that you recover from this and get back to your awesome life again.
I am really, really sorry for what has happened. It is not your fault and it was not your choice. However you don't see the power you have right now to steer your life in any direction you choose.
Your W only keeps her family intact if you are able to find grace. IF you can't there is nothing wrong with that. It is a highly personal and individual decision. You have time. No need to rush anything. Keep posting it really does help.
