What is the best thing about moving in with your partner?

Hi Girls,
I always had this question and to stop myself from stressing about plannings and preparations I was thinking about how amazing and lovely it will be to finally move in with my future husband.
I always had this thing of living with my partner and now when its finally happening? I'm all stressed and excited, all at once! Some of the married couples I know are very understanding and get everything when it comes to getting things together. I really want to bump into is his life like a blowing flower.
I am ready to face every difficulty of life but with him, because there will be a lot of new things to face after marriage but the only positive thing will be his support and love! So, my question is what is the best thing about moving in with your partner!
