welcome to SI Rocket. You'll get great advice, compassion and empathy here.
Right now, you're in crisis mode. As hard as it might be, don't let your emotions control your actions. Like Bigger said, taking care of yourself is going to be first and foremost.
*get your "ducks in a row" before you confront (see below points). Gather proof (text records etc), financial info and legal paperwork and make copies. have a safe place to keep it that your W will have no access to.
*see an attorney. You need to know what your rights are/will be. This doesn't mean you have to file right away, but it will give you an idea of what you are dealing with.
*go to your dr and get std tested. do NOT have sex with your W unprotected.
*open a bank account in your name only.
*Do NOT contact the OM. This will probably only increase contact and drive the A further underground.. It also gives him a heads up to fill his W's head with "crazy man accusing me of affair". Don't threaten to expose the A to his W (to him or your W), just do it (see below).
*If possible, have your son away from the house during confrontation. School, a friends or relatives house etc...
*Ideally, expose the A to the OM's W right before you confront your W. This eliminates the chance that your W and OM have time to get their stories "straight". Be gentle and compassionate to her (OM's W). Offer proof if she wants it and a way to contact you with questions in the future. Have no expectations of her reaction.
*Do NOT reveal your sources to your W.
*Be prepared for her to be angry, breaking down, denying, indignant, denying, faulting you, denying. Try to keep even keeled. Do NOT allow her to drag you into her drama/denying or steer the confrontation off subject. Be in control of the confrontation.
* if you decide this is a deal breaker, then you will be prepared and will have your ducks in a row to move through the process of divorce/separation.
*Ultimately she has a choice. You or him. No time to decide, mull over or think about. If she doesn't "know", then let her know that she can decide that on her own, without you...You may or may not be available for her when she comes to a decision.
**if she refused to decide, chooses to leave or needs time, then let her know you consider the two of you separated and you are prepared to execute the legalities of her choice to protect yourself and your son.
*if she chooses to end the A, Demand NC. Immediately. whether it be by text, email or snail mail. There are some great examples of NC letters in the healing library. Anything sent is to be approved by you and witnessed by you. This is NOT a time for closure or apologies. Cut, dry, done. Block his number/email. There should be NO other contact with him from this point forward, whether it be initiated or received. Also, NC with the unhealthy friends that support the A.
*Know that this is a long road. No matter what you choose to do. Your emotions will be all over the place. The stages you'll go through will be similar to the 5 stages of grief. While nothing can make this better, being prepared and having a good support system (SI, IC, trusted friends/family) can help.
I know this is a lot to take in
. There's more to it, but those are the basics (I"m sure others will add to/have better advice) Remember, you don't have to make any decisions right away. Take care of YOU first and foremost.
Keep reading, keep posting.
