The worst enemy of love is boredom and routine. When the novelty of a relationship is gone, this is where you have to work on it, because even if you love each other deeply, habits will come between you two. Especially if you live together or work together. Of course, making some efforts to spend some time together shouldn't be a chore or hard work, but sometimes it demands a bit of imagination.
Do something unexpected
Grand gestures are not always needed, and often it is the small details that are more important. Whether it is something spontaneous or carefully planned, the best gestures are the unexpected ones, those that will show your partner that you care for them. You don't have to look too far to do something nice and significant: if you are not really helping when it comes to housework, cleaning the house or put a washing on could be a great surprise for the other, especially after a hard day or week at work.
There are many things you can do to surprise the person you love and find again that spark of the beginning of your relationship. Surprise them with a dinner in their favourite restaurant, or one you both always wanted to go, take them away for an impromptu weekend, or simply cook them a dinner!
