I've know a guy for five years and we got really close. I've liked him for the five years and he told me he's liked me for the same length of time but we only dated for six days now. The problem we have is we both want to get married and have children but we have no idea how to talk about it. I'm a girl so I just want to talk it out but he's a really sweet funny guy so I don't want this to turn into a joke? Does this mean I'm in love with him? Is he in love with me?

How old are you?
Talking about the possibility of marriage and kids does not mean you're in love. In this instance it means you are young, especially if neither of you know how to talk about it.
