Think back to your first dates together - that flicker of excitement in your stomach, buying a whole new outfit (then deciding to wear something else at the last minute), the look on his face when you strut in looking knock-em-dead glam.

But within a few months, date night has probably given way to cosy evenings in front of the telly, and before long, only birthdays, anniversaries and Valentine's Day merits dressing up. No-one expects the heady rush of the early days of your relationship to last forever but slipping into laid-back domesticity can be a mistake.

'One of the biggest mistakes couples make is to stop treating each other as if they're special, treasured, and loved,' says relationship and love expert Dr Pam Spurr. 'So it's crucial that every couple continues to "date" each other whether they've been together one month, one year, 10 years, or more!

'It's easier to keep the spark alive if you know you've a special evening planned. It signals that you care enough about the other to make "you-two" time. This doesn't have to be anything costly - a candlelit picnic on the sitting room floor is fab. Plan some sexy finger foods so that you can hand-feed each other.

'Also anything where you can have face-to-face contact is best - particularly when you're both trying something new together like Latin American dance classes. Sexy, fun, with lots of physical contact, it's an ideal way to reconnect.

'It's fine to do something side-by-side like seeing a film but definitely have a drink afterwards and chat about it - ask what they thought about it and really listen to their answers, that's crucial to showing you really do care.

'Even little surprise treats can make their day. Post them their favourite chocolate bar wrapped up in pretty paper with a little love note. Email them a joke or a romantic greeting card. Load up their iPod with their latest favourite tracks. Slip a flirty and sexy note into their paperwork - the list is endless.'
