If you have sinned and hurt someone, ask for forgiveness in Jesus' name and then ask the person you hurt to forgive you, too. God sees your heart and knows when you mean it. Once you have confessed, you can give God your sin and move forward living for Him. God loves you, believes in you and will help you resist temptation if you ask Him. There is no sin that he can't forgive when you walk in faith believing in the resurrection of the Lord.
