Great advice from the website, The Loveumentary:
"On the key things that make a relationship successful:
Self Love: The happiest couples always consisted of two (sometimes more) emotionally healthy and independently happy individuals. These people practiced self-love. They treated themselves with the same type of care that they treated their partner… or at least they tried to. Emotionally healthy people know how to forgive, they are able to acknowledge their part in any disagreement or conflict and take responsibility for it.
Commitment: The happiest couples knew that if shit got real, their significant other wasn’t going to walk out on them. They knew that even if things got hard – no, especially if things got hard — they were better off together. The sum of the parts is greater than the whole.
Trust: Happy couples trust each other… and they have earned each others’ trust. They don’t worry about the other person trying to undermine them or sabotage them, because they’ve proven over and over again that they are each other’s biggest advocate. That trust is built through actions, not words. It’s day after day after day of fidelity, service, emotional security, reliability.
Intentionality: This is the icing on the cake. There’s a difference between the couple who drives through the rainstorm and the couple who pulls their car to the side of the road to make out in the rain. There’s a difference between the couple who kisses for 10 seconds or longer when they say goodbye to each other rather than just giving each other a peck… or nothing at all.”
