What does, "take it one day at a time" really mean?

Anonymous
i have been seeing a guy for over a year ... exclusively for 3 months. he practically lives at my house, at least he has slept there every single night for the past 3 months! He is younger than me and I have 2 kids. All is harmonious. I am not really asking for any long term commitment, but he often says, "everything is great as long as we take things one day at a time." Is he really and truly trying to be cautious and very careful about his decisions or is he just stringing me along until something better potentially comes along ?

he claims that every thing that I have is everything that he wants ... he wants kids, he can't wait to be a dad, he is great with mine! he has even gone so far to say that if he made a commitment to me, that my kids would deserve to have his last name!
