When you identified with the sacrifice and resurrection of Jesus you became born again; the nature of God was imputed into your spirit. As a result you now have the capacity to love; not just any kind of love but the God-kind of love - 1 Jn 4:7.
Your ability to love as God loves sets you apart from unbelievers. However your love walk will be tested constantly. These tests of your love walk are not meant to break or embarrass you. Rather as you practice your love walk through these situations you get better at expressing the God-kind of love.
Friend to be a child of God and to know God is to have the capacity to express the God-kind of love. Just as a child learns to walk you will need to learn how to develop your love walk. However be rest assured that you are not alone.
Renew your mind with the Word of God in the area of the God-kind of love and engage the Holy Spirit. Then use every opportunity to express the God-kind of love as an opportunity to develop in your love walk. Don't give up because with the Holy Spirit on your inside you will succeed.
