Hi Goose-em
to prepare yourself, there is a post her in JFO called tactical primar posted by SerJr with a target as an icon, you should deffinately read that one, its not in the library atm.
I would deffinately recommend seeing a lawyer, it doesnt mean your going to Divource but knowing your legal rights (and responsibilities) can save you a lot of trouble and give you a solid base to make further decisions from.
Collect evidence for as long as you can handle it, the more evidence you have the stronger your possition. It will also allow you to better learn to assess how your W reacts when she lies, as she will almost innevitably do when you do confront her.
Before you confront her go and Buy a VAR, keep it on you when you do the confrontation, Primarily to record her answers, dont expect youll be able to remeber much of what she says, and the confrontation is when her 'story' will be at its weakest. The VAR also protects you should things suddenly get crazy.
Before you confront you also want to make sure that you have access to all of her ellectronic communication, and taken hard copies. They will be cleaned by her at the very first opportunity after the confrontation.
Whilst it is unlikely that you will really know what you want, you can ask yourself some general questions, do you want to try and Reconcile or is this it? If you dont know then IMHO its best to follow an agnostic reconciliation path, rather than burn bridges, whatever you choose be true to yourself.
In the Confrontation itself you can expect her to deny it, then to gaslight and place the blame with you. she will lie about the extent of what has been happening, minimising her involvement, she will re-write your marital history, the most unlikely outcome of all is that she confesses everything. DO NOT EXPECT THAT!!!
She may well swear she is telling you the truth on a bible, or by her childrens lives, or any other sacred thing to you, It may well be best to allready assume that everything she says is a lie, until you can independantly verify it.
Dont provide her with your sources of information, or only reveal as little as you possibly can.
If you use any threats, then you must be prepared to follow up on them. If you tell heer she has to leave if she wont tell you the truth, then she has to leave, and dont let her back until she is prepared to tell you 'the truth' ... in quotes cause its most likely to be a trickle truth...ie just a little bit more and not the full story.
I wouldnt recomend confronting her with the kids around, perhapes if you can time it to coincide with the weekend so that you have time to sort some stuff out without the added pressure of going to work, that might be a good idea.
In general im not a fan of seperating if the aim is to reconcile, however i dont think telling a WS to leave in the immediate after effects of a Confrontation is all that bad, it can bring home the effects of their actions. It also shows that your not going to be a push over.
Wanting to knowing all the details is pretty common, unfortunately some people find this makes their mind movies worse, others find that knowing stops the speculating, which can often be worse than the reality. I assume you havent been through this before, so you wont know how it is with you until you go through it....therefore take it slowly stop with the descriptions the details as soon as you know you have enough.
Its not weird that you havent told her, its unusual but not uncommon, I knew for 4-5 days before i confronted, in those days i gather all the evidence i needed to uncover the extent of my WW's cheating. You will probably find that you cannot stop it from eating you up for too long, sadly your W may not even notice the inner turmoil that your in atm... but eventually it will take its toll and you will need to confront.
Good luck. Keep us updated on how it goes, ask whatever questions you have, come back here for support after you confront her, allow us to parse what she says, were pretty good at spotting Bullshit round here. Know that ultimately regrdless of the outcome YOU will come through it somehow.
