Hi, Numbness, so glad you found us, so sorry you had to.
Gently, how did you/your wayward deal with prior cheating? Was it swept under the rug? Did you forgive too soon without him doing the work?
Your husband is probably a serial cheater. There's an old saying, fool me once, shame on you, fool me twice shame on me.
How many times can you accept he has cheated again? One, two, four?
IMO you need to focus on you. What you want. Do you want to stay married and continue to be vigilant the rest of your life? Do you want to live in peace and faithfulness?
Please find a good IC for yourself. You've been traumatized more than once, and now you've got a double betrayal which is another level of cruelty.
Your children are grown. They can handle change if you decide you want to go the D route. You don't deserve this repeated abuse from your husband.
My husband cheated once. He understood in no uncertain terms if he does it again, there won't be any discussion, I'll head straight to divorce. No more chances. One was a living nightmare that took years to get over.
Where to I go from here?
^^^If you were my sister, I'd advise you to move on. You don't need this pain over and over, lather, rinse, repeat.
Please get tested for STDS and ask your MD if she will prescribe temporary medications to help you cope with this repeated trauma.
Sending a virtual hug......
