The sort of dating relationships that are seen today aren't mentioned in the Bible. Marriage and betrothal are the only types of romantic relationships seen in Scripture. What this means is that a Christian girlfriend should be, first and foremost, a potential marriage partner. A Christian man should be seeking a woman to spend his life with, not just someone to have fun with. If a man is not ready to get married, he should not be pursuing a Christian girlfriend.
As a man looks for a girlfriend, the most important quality she must possess (as his potential future wife and a person who will have a great deal of influence in his life) is salvation in the Lord Jesus Christ, and a life lived in obedience to Him. In 2 Corinthians 6:14, Paul tells us not to be "unequally yoked" with unbelievers. If a woman does not have faith in Jesus Christ, a Christian man would be foolish to consider her as a girlfriend and/or as a wife.
That said, just because a woman is a Christian, she is not necessarily a perfect match for any Christian man. It is important to factor in other aspects of being "equally yoked." For example, similar spiritual goals, doctrinal beliefs, and outlook on life are all extremely important considerations. In addition, it is wise to think through more practical things like energy level, common interests, and expectations about family and lifestyle. Many men marry women based on emotional or physical attraction alone, and that can lead to disaster.
The Bible provides some guidelines about the kind of character a man should look for in a Christian girlfriend. A Christian woman will exhibit a spirit of submission to the Lord. The apostle Paul tells wives they are to submit to their husbands as unto the Lord (Ephesians 5:22-24). If she is not able to submit to the Lord, she will likely not see the value of submitting to her husband when that time comes. It is important to remember that the character of submission is a spiritual quality, not a personality trait. A sweet personality does not necessarily correspond to a submissive spirit, and neither does an energetic or strong-willed personality necessarily correspond to a willful spirit. A woman will be submissive to the degree she is influenced by God's Spirit, and she will be influenced by His Spirit to the degree that she loves Him and spends time in His Word.
A Christian woman should benefit and bless her husband. She is to be his helper, according to the earliest biblical precedent set for Adam and Eve. She should be a fit helper for his mission and call. If he is called to be a pastor or a missionary, for example, he should look for a Christian girlfriend who feels the same call. If he feels a strong desire for a large family, he should find a woman who feels the same way. But most of all, according to the call put on all of us to be ambassadors for Christ (2 Corinthians 5:20), a man should choose a woman who will help, and not hinder him in this regard. She should exhibit a commitment to prayer (1 Thessalonians 5:16), encouragement (1 Thessalonians 5:11), serving others (Hebrews 6:10) and the wisdom that comes from knowing God's Word (Colossians 3:16). This is the kind of woman that will be truly helpful to a Christian man.
