That's why one man who is getting ready to propose reached out to the spouses of Reddit to get their firsthand advice on what to expect from married life and how to make it last. Below are 15 pieces of relationship wisdom from couples who know a thing or two about wedded bliss.

2. "Keep pursuing your spouse after you're married. Go on dates. Buy her flowers randomly. Hide a note somewhere that she won't find for a few days. Offer to do something that's usually her responsibility, just because. Let her know you love her -- not just by saying so, but also absolutely by saying so!"

7. "There's this new sense of 'realness' to it all after you're married. It's kind of hard to explain, but you're going to wake up some days and just look at your wife and say to yourself, 'Wow, she's going to be here every day for the rest of our lives.'"

12. "Learn to laugh stuff off. Living with someone else can be a challenge at times, and little stuff can begin to feel like big stuff. But you have a choice in how you react. You can decide whether some little thing that drives you crazy is a personal foible, or a ''Hill You Want To Die On Because If She Really Loved Me She Would Stop Doing It So It's Now A Metaphor For Everything That Is Wrong With Our Marriage.'
