I very am sorry that you are here.
The first thing is that you are possibly still in shock, DDay 5 days ago is so recent. You must take some actions to preserve your own health. Remember that you must hydrate and eat. Exercise is also helpful. Please no alcohol.
If you find that you cannot eat, try smoothies or the protein shakes that bodybuilders use. You need your strength to look after the children.
The second thing is that you have zero responsibility for WW stepping outside the M. Whatever excuses or justifications WW has, they are bullshit. Nothing you said, did, or did not do caused WW to stray.
WW admits to PIV sex 20 times, and a BJ at the first meeting. Wow that is very bad.
I urge you not to make an immediate R or D decision. You will be on the emotional rollercoaster and your feelings will fluctuate wildly. The children will tie you to WW for years in any case. If you are in the USA, it is likely that WW will be unable to take the children out of state without some sort of court hearing.
You must start a journal immediately documenting how you contribute to child care.
Especially document any instances where WW puts the A and AP above caring for the children.
If you feel that you are too confused and stressed to make rational decisions the 180 strategy available in the healing library will help you. I hope that you give serious consideration as to trying the 180, it really will help you to gain much needed clarity of thought. The 180 is the first article in the article section and also Q11 in the BS FAQ. The 180 is counterintuitive and difficult to maintain, but it is very effective: it will project a calm confident independent image to WW. There is much more useful information in the healing library, please read as much as you can. You do not need to make any big decisions immediately, and in fact you should probably wait a while before taking major decisions. Note the full 180 does not help attempts to R, in R some aspects need to be changed.
I am afraid that for the moment you cannot believe much that WW tells you. WW has already demonstrated that she is not the caring spouse that you thought she was.
You should make every effort to find as many details of WH’s behaviour as possible. Knowledge really is power. You need a full backup of WW's phone ASAP. Very soon WW will delete all that information.
Forgiving too quickly or without sufficient detail is rugsweeping, and often leads to problems latter. Unaddressed issues fester like an infection deep inside the body: whilst on the surface the wound seems to have scabbed over and healed.
Make a considered decision to try R, if that is your preference.
You need a full panel STD test. Remember some STDs such as HPV have a typical incubation period of 2 years, and can be much longer. As HPV without active lesions
can only be tested for in women, WW needs full panel STD tests for years to come.
You should also consult a lawyer to understand the legal situation. This is self protection.
A written timeline of the A from WW is highly desirable. Ask for this.
WW should hand over passwords to all electronic media.
I strongly feel that you need to investigate further. You need access to WH's phones and email accounts. Technical help can be given on SI if needed.
If OM has a BW or BGF, you most out the A to her ASAP. Find details on OM as a matter of urgency.
This is strongest step you can take to ensure the A is dead and save your M. Do not tell WW you are informing the OBS, just do it. WW will react poorly to the outing, but tough that is all on her. Consider outing the A to WW's family.
Do not tell WW that you are on SI, and do not reveal any information sources to WH.
Please take the advice that works for you from posters here and disregard that which is irrelevant. Only you can decide what is applicable to your situation.
Remember that more relevant details you post, the better the advice you will receive.
