3. Say “I love you”
Now a lot of people tend to forget the very usage of these three words. Yes, you two are in love, you know it, she knows it, the whole world knows it. But how many times do you actually say it to one another? It might not seem like a big deal but saying these words just out of the blue or casually mentioning it to her will delight her beyond her wits. Imagine if she is sitting there doing some work and you just walk to her and kiss her forehead and tell her “I love you”, you can bet she will have a huge grin on her face for the rest of the day.
