Do you ever feel sabotaged by him/her? I know how you feel! I thought I was alone until I took this student's survey for her PhD. Now I want everyone to know about it. The questionnaires include some on weight and sabotage and then some on the quality of your relationship. It took about 30 min and then she donated $1 to charity and I entered a drawing for $100. Taking this survey really helped put things in perspective. Here's the anonymous survey link (it's hosted by her school, Clark University) or you could just Google PUBS-WL.
