A lot of people think that falling in love is what it's all about — but staying in love can be way trickier. But a lot of it comes down to focusing on the little things your partner does that still light you up. "Positive thinking can increase how much love you have for your partner for several reasons," Yvonne Thomas, Ph.D., a Los Angeles-based psychologist, tells Bustle. "First of all, if you are already thinking positively in general, you are much more likely to notice and appreciate those qualities in your partner that you love rather than take these characteristics for granted or or overlook them. Also, if you typically tend to engage in positive thinking, you are likely to be a more open-hearted person in general, as well as towards your partner than someone who tends to be more of a negative or even neutral kind of thinker."

And these little things can vary so much. In fact, this AskReddit thread had people sharing the insignificant things their partner does that makes them fall in love all over again. Because it's not always about big moves and sweeping gestures — it's really the everyday behaviors that keep your relationship alive.
