Hi,
I'm sorry for you and the kids!
I posted this somewhere else and hope it will help at least somewhat:
"A couple of suggestions to think about, if I may:
- talk to a lawyer about protecting yourself, your boys, your assets
- after talking to a lawyer, set up family counselling for the children, it will help them immensely and hopefully look good in potential custody disputes. Children are greatly influenced and perceptive of such tensions between parents.
- consider counselling (paid/pro bono) and/or support groups for yourself
- carry a VAR at all times and take other precautions to defend yourself against bogus abuse etc. accusations,
- document everything (your care for boys, her care, detrimental conduct,... to boys,) for custody purposes. It could get ugly and your kids need you as much as possible in their lives
- don't drink/get drunk
- as hard as it is for you, from hereonin, you'll have to be the hero for your buys and take extra super care for them, especially to make up for her detrimental conduct, role-modelling,...
- reach out to your close ones for support
- make safe copies of evidence pointing to her affair
- think about (after talking to your lawyer) asking her to go to marital counselling, church counselling etc. with you, upon certain conditions (verifiable no-contact with OM etc.). Notify her in writing of that (remember - document! so you can prove in court if you get divorced). If she isn't willing to discuss it, set up one or two meeting with a counsellor for both of you and notify her when&where. If she doesn't show up, express disappointment (in writing/email). Again, it might help you save your marriage, and at the very least will perhaps help you in divorce/custody proceedings.
- make sure you don't let her in on what you're doing to protect yourself
- after having sufficient precautions in place and after talking to your lawyer, expose her affair
I'm sure others, more experienced will give more and better advice.
Don't trust her to play fair and don't expect her to do what's best for the kids. Since she had/has an affair, she clearly isn't thinking in the kids' best interest."
I'm glad you're taking decisive actions and hopefully you'll make the best for you&the kids out of this extremely horrible situation!
Looking forward to hearing more from "Mr. Cheated-Husband/Father/Papa-Bear"!
Best wishes
