See I have a friend that went behind my back and went with my ex though I still had feelings for him.also she calls me her sis and when she does that it makes me want to kick her a**... am I wronge for feeling that way cause I know that I have moved on and all but at the time that was kind of hard for me but I'm still having trouble trusting her as a friend. Do you think I should be her friend after what she did?should I forgive her?I just don't know... I am so confused please help me determine weather I should just stop talking to the both of them are not...
