Congratulations and best wishes. It is very important for all concerned that you discuss this not only with the new bride to be, but also with your children, and attorney. Put it in writing, and ensure all parties have a copy of your wishes. This prevents fights, law suits and possibly murder at your death.
I am speaking from experience, my father-in-law was a widower for over 40 years when he met the "lady of his dreams." She may have been the lady of his dreams, but she was a nightmare for his kids. Upon his death she refused to do anything with the body, my wife and her brother and sister had to take care of all the arraignments. The lady of his dreams didn't even show up for the funeral. She refused to allow his children access to anything, especially some of the things left to them by their mother. Everything the old man owned she took, of course a large percentage of it went to her children. One of his biggest mistakes was selling his house and property and buying a new place with her, she got everything, even though a portion of the property belonged to the childrens mother.
What is funny, before he died, everyone though this was the perfect match, both of them got alone well with each other's children, They visited and spent time with children and grandkids. After he died, she pulled out her broom and turned into the biggest witch I ever met. When we were notified that the father-in-law had passed away we went to the house to see about her, she met us at the door, cussed us out and spit in my face. Prior to the death she met us at the door with a big hug and kiss. After the funeral I told her, "I forgive you for spitting in my face, but just remember, I will have the pleasure of urinating on your grave when you die."
Do what is right for your children
before the marriage, you will rest better in the ever after for doing it. :roll:
