Belinda86,
As you can see, you are not alone in this. Many have been in the same place. You have been given some good advice in these post, continue to pray. Some of the best advice that has been posted:
Stay away from this person.
It is not your fault! Often the abused feels that they caused the abuse. YOU DID NOT CAUSE THIS! That is a lie strait from hell.
Do not write anything that is not true. I suggest that you do write something, but write down what did happen.
Seek Christian Counselling. Talk to a Pastor and see if He can or if he knows someone who can do this type of Counselling.
Most importantly do not hide this issue, anytime abuse happens it needs to be reported.
Finally seek God! Ask Him to begin to show you how He is going to use this part of your life for the Kingdom work He has for you to do.
I was abused as a child as well, you may read the beginning of my testimony in the testimony section, titled "God's Grace (part 1). God has used that time in my life to make me who I am, and I praise Him. I am now a Associate Pastor and Youth Minister at a small Church in Florida. God has used my life to reach others, and for that I am thankful.
Let me know if I can help in any way.
In Christ Service,
Humilis
