Keep the passion burning in your relationship by committing to a plan.

Have a once-a-week "date night" for starters, says Ms Violet Lim, founder of Lunch Actually, a well-known dating service here.

Ms Lim says: "If you have children, get someone to help you look after them for a couple of hours, and just spend some time 'dating' your partner again, be it at your favourite restaurant, watching a movie or just strolling in the park."

Engage in something unexpected, like picking up a new hobby together or surprising her with a present, even when it's not a special day.

She adds: "When we do something new, we will feel more alive and energised." Hopefully, positive energy gets channelled to your relationship.

Psychiatrist Tommy Tan says couples need to "make time" for each other.

Explains Dr Tan: "People in relationships become depressed because they lack communication with their partners. How to have a healthy relationship when you can't find time to talk?"

So pen it down. Make an "appointment" with your partner, whether for dates or even sex.

Adds Dr Tan: "When I tell clients that sex is never spontaneous in a marriage, they look at me with bewilderment. The reality is that most couples are too busy with children and work."

When you finally get that private moment in your bedroom, make it fun by playing games like erotic charades, says Her World magazine in its December 2011 issue.

Singapore's top women's magazine quotes Ms Maggie McKenzie, a UK psychotherapist, as saying: "If we see sex only as serious, it can make us very anxious, so it's healthy to be silly about many of the things we do sexually."

Now that tip could just save a relationship.

Yet it's also important not to take your partner for granted, says Men's Health magazine on its website.

You can rekindle your romance by "keeping things fresh".

For a change, do what she wants to do on a weekend.

In one study, where 73 couples were tracked over 13 years, the happiest couples were those who found enjoyment in sacrifice.

Psychologist Howard Markman from the University of Denver says: "Find out what your partner really wants to do (even shopping for curtains), make it happen and enjoy it. It'll save you thousands in therapy."
