Post an anime with a love story that doesn't end with them just getting together but continues with having ups/downs, a wedding, children, and/or family life.

I recently saw Itazura na Kiss and I absolutely loved that the anime was only half done when they got together and then the rest was their crazy life together. It was such a cute and sweet breath of fresh air seeing a "real" relationship that had a lot of ups and downs to it. I can only think of one other anime that did this as well (and I bet I see it in the answers). Post ones you know that takes the couple though life... or at least some trials.
