I was officially divorced last June or July some time. I'm hoping that the attorneys will hammer out a child custody settlment and a property settlement at a trial currently scheduled for early May (it's a long story). My point is that I've chosen divorce - I'm not opposed to on principle but I don't recommend it. I mean, I believe that divorce is the right thing for me but my d-day was 5 years and 8 months ago.
Divorce may be the right thing for you too, Jen but unless you or your kids are in some kind of immediate danger, please take some time to think it over. Two or three weeks after d-day, I was in no condition to make life-changing decisions.
I'm in favor of taking a strong stand with an unfaithful spouse. I think you owe it to yourself and your kids to be clear that his behavior is not acceptable. But please also remember that it is pretty common for people in affairs to find it very difficult to "let go" of the other person. There are many people here who can tell you that it didn't "end" when their spouses said that it did. I don't mean that continuing an affair after it has been discovered is okay. Obviously it isn't. But it's common. This may truly be the last straw for you - it may have killed your desire for reconciliation. It's just that it might be worthwhile giving yourself time to decide what to do next.
I hope that you are taking especially good care of yourself now. For most people, the stuff that you are going through is traumatizing. It isn't a minor shock. It is traumatizing in the deepest way. My apologies for the direct advice but for the sake of yourself and your children, I hope that you will ask for some professional help - someone who understands the impact of ongoing infidelity and has some ideas for treating it now rather than later. You have alot of options. A professional might be able to help you figure out which ones could work best for you.
