* You can disagree without blowing up.

Here’s a massive clue to contentment within a relationship. All couples disagree. Some say they don’t but I feel like they’re a little repressed. Conflict can be healthy but you’re in trouble when every little niggle between you blows into a storm, turns into a cold, stony silence or ends with a slam of the door. In an ideal world, disagreements open your mind to your partner’s perspective; they can help you move forward in healthy ways. Easy relationships are about being able to disagree, apologise when necessary, and move on smoothly. If you can do that, it’s a big win.
