He's still working on me

I dislike my neighbor. I don't hate her or wish bad things on her, I am happy to help if necessary. I just don't like to interact with her. They visited our church on friends day a few years ago and decided we're nuts and wouldn't let her kids play with mine anymore. She's been aggressively in our business every chance she gets. There is a long list of things I think she did,but can't prove it was her. There is a shorter list of things I KNOW she did. The main thing is she really hurt my girls. They had been friends with those little girls for a year or more. My middle child cried and cried over this. She told hers that they weren't even allowed to speak to mine. Now their family is going through some bad times,the details of which I wish I didn't know and won't share. She has evidently recommitted herself to Christ. Ok, I don't know when she committed the first time but I have never seen any fruit.. Last night she emailed me and said that her "bible teacher" I assume from the large Baptist church they attend, reccommended that she find a "spiritual mentor" and she asked me to do this a couple of times a week. I feel like this woman has always been destructive,unkind and manipulative. I feel like this is some sort of manipulation,as though she's using my christianity as in "in" for some reason. Why wouldn't the Bible teacher rec someone in their own congreation? Something smells fishy,but I also feel like I should do it. Clear the air about some things. Set some firm boundaries,and have a Bible study or some sort. I have prayed for God to use me, let me minister to others,let my life be a light on a hill..this isn't what I meant lol. I feel like to do this I have to have full forgiveness of her and oddly enough I realized that I don't want to forgive her totally. I seem to enjoy that teeny little grudge. I'm going to have to put that under the blood today. I can't just walk around unforgiving. This other stuff, we'll take it slow and see how it goes.
