A good verse for some girls to learn

Song of songs
8:4

Young woman of Jerusalem, I charge you: do not stir up or awaken love until the appropriate time.

some girls have 'crushes', And this Bible verse tells us that involving ourselves in that is wrong, Also, having crushes makes us impure for our future husbands, and what if you continue having a crush on some boy, and he marries someone else, you will be heart broken, and you will wish for something you can't have, Jealousy steps in. and, what if you miss the man God wishes for you because you want this other man? will that be truly following God's will? and if the Boy you have a crush on is NOT God's will, and you marry him later on, you will most likely have an unhappy marriage, so, here what Solomon had to say, do NOT involve yourselves in impure love. here what the Bible has to say.
