Choose Inner Peace...
"Forgive. It doesn't erase their crime but why should you do the time. Let go of resentment."
Forgiveness often times, depending on the circumstances, is very difficult to do. However, perhaps viewing it as something you need to do for yourself and not the person who betrayed or harmed you makes it more palatable. Forgiving can bring inner peace which facilitates happiness. Let go of the pain from the past, choose happiness and move forward on the wonderful journey that awaits you.
In the end, it is your choice...
