Considering that pretty much every piece of storytelling telling us that a relationship is the only way to feel fulfiled, there's not nearly so much on maintaining a relationship.
Even the most romantic of meet-ups can end in tears. Let's face it, if Jack hadn't drowned in Titanic, it would have been a matter of months before the reality of living poor in New York became too much and Rose went crawling back to her family cap in hand.
A relationship expert has shared some tips on how to actually maintain a relationship in the day to day stresses that life can throw at us.
Some of it might seem obvious, but it makes a lot of sense.
Jo Hemmings explained how to identify potential problems in a relationship before they get out of hand.
Here are five things to keep a look out for and how you can remedy them.
Neglecting each other
This may sound obvious, but it's important to make time for your partner - even during a hectic week.
Hemmings said: "Neglecting your partner can lead to feelings of loneliness and disconnection, which can strain your relationship.”
Venting work stress
Of course you can and should confide some work-related problems if it is getting you down, but it might be a warning sign if sharing gripes on a daily basis starts to become the main topic of conversation.
Hemmings said: "This can create unnecessary conflict and tension in your relationship.
"Instead, find healthy ways to manage stress, such as exercise, meditation, or talking to a friend.”
Failing to communicate
This one's all about being clear about your expectations and talking things through - bread and butter stuff.
Hemmings said: "Avoid ignoring calls, texts, or other forms of communication from your partner.
"If you can't respond right away, let them know when you'll be available to talk.”
Not running big decisions past each other
If there's an important decision that will affect your partner too, they need to be included in the conversation. If you're making these kind of calls without them, your relationship could be in trouble.
Hemmings said: "Even if they're busy, it's important to include them in the decision-making process to ensure you're on the same page.”
It's the old adage of needing to look after yourself before looking after anyone else.
Hemmings said: "Avoid neglecting self-care during a busy working week.
"Make sure you're getting enough sleep, eating well, and finding time to do things you enjoy.”
