Thanks everyone!

I emailed her back in May saying that we should put any problems we have behind us and get on with our lives. I told her I miss my sister and would like her back in my life. She responded with an long email rehashing everything from 3 years ago and said as long as I still feel that way, she wants nothing to do with me.

My mom sent her a christmas present. She sent my mom an email thanking her and again, rehashing everything and stating as long as my mom agrees with what I said to her 3 years ago, that she can not have a relationship with my mom.

There is just no letting go for her.
