I feel the same way as you. I have no plans to get married again. I'm concentrating on the good things from my marriage. Our children are such wonderful people. And I also think that you should set the rules before you get married. I didn't have a prenup and really wish we had. We started this marriage together without much money. Created a lot together. It got very complicated at the end. Precisely because we hadn't settled anything.

I wouldn't want the kids to have to compete with a new spouses for the inherentence. When my husband and I are both deceased, it should be all theirs.
