It's ok. Welcome to the beginning of your life. You do realise that love cannot be forced don't you. Just keep trying. It is not the end of the world. The first few times of heartbreak is hard. You will get used to it. If that person was meant for you, God will unite you with him.
If it is not too late,
1. Tell him how you feel to his face.
If he says no, take it like a woman and move on. He doesn't know what he is going to miss out on.
Always maintain your integrity and self respect. Don't undermine your self worth. You will find the man of your dreams if it is meant to be at God's time. Wait with patience. Pray
Surrender it to Jesus. You will be fine. God bless you
