Trust is broken. I would get a lawyer to protect yourself and I don't know the laws in your state but not sure what adultery gets you. Where I live you can file for divorce with cause for adultery if you can prove it. I mention this only by your comment of wondering if she is meeting the OM somewhere. I almost hired a PI for my situation but it would have had no legal implications ....check on yours if that is your suspicion.
Your wife sounds a bit like mine in terms of trying to steam roll you alot and treating like a pos. I did stand up to mine during the R but not enough. I do now and don't let her push my buttons...push right back. I would say do the same and dont let her walk on you. Otherwise if things don't turn around for you she will do the same moving forward. Have fun at the water park!
