A single christian woman should not dance to the tune of the world. Her life should be totally committed and surrendered to God. Every part of her life should belong to the Lord. She shouldn't surrender some aspect and leave out the rest.
Psalm 37:5
Commit thy way unto the LORD; Trust also in him; And he shall bring it to pass.
Everything she does should not be fine without first of all acknowledging God. By so doing, she can be rest assured in according to proverbs chapter 3 and verse 6 that He will direct her path. If God doesn't direct her on how to life her life and which direction she should take she may venture into the wrong path.
God should be the first person in her life. She should be fully aware of the fact that her relationship with God is more important than her relationship with anybody else, and she shouldn't let anything compromise that relationship.
