How?

"Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from your, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you." Ephesians 4: 31-32

When someone hurts you, do you lash out at them? Do you want to throw mud? Do you want to give as good as it has been given to you? According to the verses above, that is not what God would require of His children. He wants us to put away all bitterness, wrath and evil speaking and learn to speak in love. You may say that God sure does require a lot from me. How can I speak in love, when I have just been hurt by someone I thought cared about me? It is just not easy.
God doesn't want you to do it by yourself. He wants you to ask Him for help. He will give you the strength you need to speak in love. He will help you to be kind, tenderhearted and forgiving. Just ask HIM, He is listening and willing to help.
From personal experience, it is not always easy. I have learned to let God be in control of my life. When He is in the driver's seat, I do not have to worry. He will take care of me. If He is willing to take care of me, I am sure He will take care of you.
Blessings to you!
