Tell your mom in a kind tone that you will consider her suggestion in this matter, but that you do not feel compelled to act on it at this time. Between you and me..and you can share or not with mom, I don't think that Christ would want you to pretend to accept feelings that you don't really feel. You've been hurt and angered by this and it may well take some time to FEEL that you can try and forgive. Prayer is a wonderful thing, but we have free will and from experience I would say that even if you embraced the concept that forgiveness was a good thing and wanted to be able to do it...you might still need to pray yourself to be ABLE TO TO IT..I have a similar situation in my life right now. Some one went out of their way to lie and cause me extreme financial hardship...it is going to take me several years to recover from it..they LIED to cost me money and I had not done anything to them... As a Christian, I KNOW I "should" forgive them, but I can't do it yet...I'm hurt and angry, and struggling. I suppose there is a lesson here for me to learn and maybe forgiving my enemies is part of it...so I am praying that God will help me understand and take a leap of faith in my ability to forgive...but I haven't yet been able to do it...I'm just not ready in my heart yet and I am not going to lie about that. It's hard, because when we carry and hold on to anger and hate...we do harm ourselves more than the ones we are angry with...I believe this to be true...rage, anger, sorrow can add to illness...physical, and emotional...but letting go of it can also be hard. I don't know how to have a dialog with my "enemy" at this time...perhaps you can figure out a way to do so with yours. If she now says that she was wrong, and spoke cruelly...without thinking of how it would impact you...maybe you can work through it at some point. If there is any small truth to what was said...and that is eating away at you to have had it flung into your face...then that too might be addressed by you to her. Good luck...it's assuredly not a comfortable situation for anyone.

Tell your mother that you have decided to forgive and forget ( but you don't really have to if you don't want to ) and let her be at peace knowing everything is ok. My mother was the same way and I pretended all was well and she died thinking the family was all sweetness again. Do it for her....and who knows someday you may forgive her for real. GoodLuck!
