Six years is a long time to date someone, so when your anniversary rolls around, choose an appropriate gift. You likely know your significant other very well by now, so choose something that fits her personality or hobbies. If you are planning on getting more serious with your relationship, choose a gift that will give her a hint as to your intentions.
Electronics
Select electronics for your partner on your sixth dating anniversary. For example, if he enjoys reading, select an electronic book reader. If he is a music lover, choose a set of speakers so that he can listen to his MP3 player without ear buds or a subscription to a satellite radio service. A boyfriend who enjoys traveling will love having the assistance of a global positioning system, or GPS.
Engagement Ring
After six years of dating, you likely know by now that you want to spend your life with your girlfriend. If you both want to eventually get married, go ahead and bite the bullet. Buy her an engagement ring and propose to her over a romantic anniversary dinner. Alternatively, propose in a place or doing an activity that is special to the two of you.
Trip or Experience
Give each other the gift of a trip or experience that you want to do together. For example, head to a city you have never visited and check out the sights together. Spend a weekend at a beach resort and sit on the beach all day long together. Alternatively, have an experience together, such as sky diving, visiting a winery or seeing a play.
Personalized Item
Select a personalized item for your significant other. For men, consider a leather wallet, a set of cuff links or a watch with his initials printed onto it. For a woman, you can select a piece of jewelry engraved with her initials or a bathrobe with her name printed on it.
