If you want your relationship to stay strong and healthy, give thoughtful gifts that show you love and know your partner. Your boyfriend's 22nd birthday is an excellent opportunity to give him a meaningful gift that will help to communicate the depth of your feelings for him and strengthen your bond.
Give a useful gift a thoughtful and personalized touch. For example, give him a new golf bag with his initials monogrammed on the side. If he's about to take a new job, give him a stylish watch or cuff links engraved with a short, loving message. You could also borrow his casual company polo shirts or his favorite hat and have his name embroidered. Or, buy a plain wooden frame, paint it yourself and put a photo of the two of you inside.
Sweep your boyfriend off his feet on his 22nd birthday. Blindfold him and take him to a luxury hotel suite for the night. Order room service and enjoy relaxing in the jacuzzi. Or, send him a singing telegram with flowers and candy. You could also write him an original poem, or write the story of your relationship, have it bound and give it to him as a book. Other options include creating a web page declaring your love for him and creating a "love coupon" book. To give your romance a practical touch, buy him a series of $10 gift cards from his favorite fast-food restaurants and hide them throughout his car and home.
Send your boyfriend and his closest friends on a guys-only weekend. Get them tickets to a sporting event, passes to a golf club, and send them off with a cooler full of their favorite beverage. You could also pay for your boyfriend to attend a class in something he's always wanted to learn, such as a foreign language or exotic cuisine cooking. If you're low on cash, just pack a picnic basket full of snacks and take a weekend road trip. Before you go, research the surrounding area and hit the most interesting places you can find.
Taking an interest in your boyfriend's interests can be a gift in itself. If he loves music, consider upgrading his MP3 player or getting him guitar lessons. If he's a car fanatic, get him tickets to a professional race or buy him a series of model cars to assemble. Get a book lover an online book rental service subscription and a news junkie a subscription to the industry's leading publications -- both electronic and print, so he'll always have access.
