Idaho is a joint custody state, no matter what proof you have he still has a right to his children, when my husband went for sole custody of his children from an extramarital affiar (the children were born during our seperation) everybody all but laughed at us for trying to get sole custody, well we did get it but only because the birth mom made no attempt to fight it, so it may be almost impossible to get what you are asking for, even under hardship conditions.
Know from someone who has been in your place, and through all the emotions you are feeling. Ask your self these questions... Are you doing this more out of your hurt and anger? Is this really the best option for your boys? And the most important Q would be who benefits the most from your hurt and lets face it revenge, which is all very natural!!! Your boys need thier dad in thier life on a regular bases, he deserves the chance to be thier dad, No one can take that place not even the worlds best step father, and vise versa. Step back from the situation, it is very hard but well worth it, and look at it as an outsider, how would you advise the outsider to handle it? The best thing you can do is let it go. Move on. tell him no thank you to the relationship for you and him, if that is what you really want to do, and be very sure of it, no wavering. If you think he is worth a second try then fight with everything you have in you but go in knowing it may not work out and in the end at least you can say you tried. The best revenge for you and your boys, if you decide it is over, would be to move on and become independent and happy to find another man one day who will love you and your boys unconditionly (SP) who will value you as the woman you are and be your shoulder to cry on. That is your best revenge, that is your revenge, I believe what comes a round goes around, the grass always looks greener on the other side, but what my husband found out was it isn't and sometimes it is a bigger hell, his time will come and you can sit back in your happy life and know he is miserable and deserves what he gets, just make sure to protect those precious boys they grow way to fast and help them to build a healthy relationship with thier father.
