I seriously think it is so stupid when people say that they can't marry someone until they live with them! So are you going to live with tons of different people until you find the person who is suitable enough to live with and won't drive you insane?! Pretty fucking stupid in my opinion. Now if people move in together before and it's a mutual decision then that's different because you're not going from one person to another to see who or what you like better. I'm happily married, expecting our first child and didn't live together until we got married. When people say the first year is the hardest it's because they make it that way, or put it in their head that it's going to be difficult. It's all in your hands on how your marriage goes and not going by what other people say.
