Family...or, that's what they call themselves...?

Wow. I think you don't need people like that in your life. That isn't family. I am kinda related to some people like that and I don't let them bother me. She is probably jealous. But let her know you can't be bought. If you haven't used the gift card maybe you should send it back to her if you really feel that way. If your looking to maybe patch things up then I think you should find a family counselor. But yeah one of my favorite things from Dante's Inferno, the deepest circle is hell is reserved for betrayers :)
