I guess then, the question is - what form of forgiveness are we speaking of? Here is the definition I found on Dictionary.com:

for·give http://cache.lexico.com/dictionary/g...una/thinsp.png –verb (used with object) 1.to grant pardon for or remission of (an offense, debt, etc.); absolve. 2.to give up all claim on account of; remit (a debt, obligation, etc.). 3.to grant pardon to (a person). 4.to cease to feel resentment against: to forgive one's enemies. 5.to cancel an indebtedness or liability of: to forgive the interest owed on a loan. –verb (used without object) 6.to pardon an offense or an offender.

To cease to feel resentment towards a perpetrator, for me, can be done with work. However, I don't feel that I need to "pardon" my perpetrator for her crimes against me in order to heal. I will not excuse her actions.
