Answer:
If one does not forgive because they are not yet ready emotionally, they must make the intention to forgive and ask Allah, Most High to open their heart and fill it with mercy. Reading the stories from the life of the Prophet Muhammad (Allah bless him and give him peace) is beneficial in this pursuit.
Forgiving someone does not mean that one must be best friends with them. Forgiveness is to overlook the fault of another human being because Allah, Most High loves this and will show you forgiveness.
