Based on your other questions, you are an adult. Do not take sides. Maintain open communication between both of them (you will need this for grandchildren), but keep your conversations confidential - do not share what one is telling you to the other. Basically, do not share gossip even if you think it is harmless.
Try to keep visiting as equitable as possible. Make time to visit one after visiting the other.
Depending on the situation every divorce is different. But all you need to remember is too stay strong. If you stay strong, the process will be better for the whole family. Talk to friends about it and don't keep it bottled up. Many parents are getting divorced these days. Yes you may lose some family traditions, but you also get the chance to create new ones! Just stay positive, because less conflict in the house is always a better thing.
Remember they love you and it's not your fault. Do not get involved or take sides believe me there's stuff you will never understand until you go thru it. If one bashes the other, kindly tell them it hurts you to hear. Stay strong, you'll get thru!
Well for one dont be clingy like dont be like i dont want you two to seperate. Instead see it like this if they cant be with eachother anymore then nothing can keep them together and if they were to stay together things would get worse. Also be open to both dont take sides and talk to them the same. Dont make one feel less than the other.
