Help her feel good about being your girlfriend. When she feels important to you, she is more likely to accept or even encourage you to enjoy yourself with sports. In his book, "Communication Miracles for Couples: Easy and Effective Tools to Create More Love and Less Conflict," Jonathan Robinson says all human beings are the same at the core, with a need for acknowledgment, appreciation and acceptance. When you tell her what you like and appreciate about her, you make deposits in her emotional bank account, giving her a sense of security in your relationship. When she feels secure, she is less likely to feel a need to compete for your attention.

Include your girlfriend in your sports activities when you can. Whether by playing, watching or attending a sports function, women can enjoy sports and competitive activities, too. Engaging in sports together can enhance your relationship and gives you a chance to spend time with both your passions.

Share information with her about teams and players. Use online videos, movies or magazine articles to familiarize her with your favorites. When you help her build an emotional connection and enthusiasm, she might even become as avid a sports fan as you are.

Spend time with your girlfriend doing things of her choice on a regular basis. Reciprocity is important to relationship maintenance. You can gain even more points if you find ways to show enthusiasm as you take time to participate in her favorite hobbies, even if those include shopping, gardening or watching romantic movies. Turn about is fair play, as they say.
