Let's face it: Most romantic movies end right as the relationship is beginning, so we don't see the hard parts of a long-term relationship.
It's never as easy as the movies make it out to be! Relationships take work, communication, and compromise.
So if you're in a long and successful relationship, tell us your secrets! Is it all about positivity and supporting your partner?
Is being a good listener the key? Or is there something else you've learned that you're convinced nobody else knows?
We want to hear your advice! Tell us the key to a healthy, happy, long-term relationship (and how long you've been in your relationship, if you want!) in the drop box below, and your submission might be featured in an upcoming BuzzFeed Community post or video!
