Be playful, suggests Alexandra Churchill in "Girlfriend: Top 10 Qualities Men Are Secretly Looking for in Women" for YourTango. Laugh at his jokes and tease him gently about his imperfections. Showing amusement when he cracks a joke will boost his confidence, and poking playful fun at him -- without going overboard or insulting him -- will make him feel comfortable showing his goofy side. Don’t make him self-conscious, but it’s okay to giggle if he stumbles over what he’s trying to say or pulls a clumsy moment. Guys want a girl with a lighthearted sense of humor.
Communicate clearly. Guys aren’t the greatest at picking up on subtle cues or figuring out what’s really going on in a girlfriend’s head. Help him out when you're unhappy with something he has done by explaining honestly and concisely what you’re thinking and feeling. It may be tempting to give him the silent treatment or let him figure out why you’re upset on his own, but he’s not going to decode your message. Provide some input or the unhappiness will linger.
Support him when he’s feeling down and don't nag. It’s more important to be there for your man when he’s struggling at work or facing a family problem than when he needs fashion advice or isn’t managing his money the way you would. Show up for him when he truly needs it.
Don't be afraid to show you are intelligent and compassionate, according to a survey psychologist Shawn Smith conducted and reported in "Psychology Today." Your guy needs someone who is comfortable with her emotions and can help him be kinder and more aware of other people's feelings.
Maintain your social life and get involved in his. Meet each other’s friends. Be nice to his and don’t spend the rest of your evening telling your guy which friend was a chauvinistic pig and which one was dumb. They’re his friends -- accept them. Introduce your man to your friends, too. Spare him the gossip and catty talk. Save that for your girls’ nights.
