3. if the #2 is the case, truly let go, move on; if you want to, start dating and don't hesitate to indirectly let your h know that you're doing it
I agree with your points, except for #3. In my state, if I had a boyfriend or committed adultery, I was told by my L and the judge that would affect our D financially. It's ok for H to A, b/c he is paying the child support/custody but I guess if I had a boyfriend that would change. Doesn't seem fair, but there it is.
Also, I personally don't agree that dating is right for a married person. I couldn't sleep at night if I did that. I also think I wouldn't be interested in someone that would date a married person, which is what anyone we would date would be like. I mean not the kind of person I could admire or respect. I also would think if you and your WAS are both dating, you might as well just give up 100% on your M then. Because most likely it will be over no matter what.
I know some people here date, but just think it adds extra complications and stuff. I think DBing is more to focus on your and your family and not an OP. Karen
