Im so sorry to about your parents divorce. I know somewhat what you are going through E.. My husbands parents divorced last March after almost 40 years of marriage! My father in law is already getting re-married this April! We are all not going to the wedding, a big reason is that it is in Nebraska, but I also dont think the kids are ready to see that. My husband is going is all. I also have a 5 year old and a two year old and are a stay at home mom. When we finally explained it to our five year old son we just explained that Grandma and Grandpa live seperatly now and that Grandpa has a lady friend. We didnt say the word divorce. We didnt make a big deal about it so he didnt either. Now, my son is super easy going and I think that helps. My sister in law also has a five year old, but a girl and she is taking it much harder. The first visit Grandpa makes out here with his new wife will be very tough. I am not looking forward to that. I guess my advice would be to not even explain it to your 2 year old. Much too young to understand anyway. Do you live close to your parents and see them often? What helped us I think is that Grandma and Grandpa live far away so it wasnt uncommon to have one or the other come for a visit. As is the case with my sister in law, they lived close to g/g and did things with them often, which makes it harder. Visiting them has been a different story. Lots of wheres Grandpa/Grandma? We would just casually say "Grandpa is at his house". Im sure we wont be able to get away with that for long, but for now it works. I have a girlfriend whose parents divorced when she was young, but now her kids have lots of questions. What she does is sends the kids to her parents with the questions. That might be an option once your kids are older. Let them explain themselves. But, what worries me about that is that there is no "filter".
I will pray for you and your family. Good luck with what you decide. Please post how things are going. K.
