I kind of asked the reverse question in another thread, as someone who lost weight and now sometimes feels an attitude from other women.
For those of us struggling with weight loss, do you ever project an attitude when being introduced to a thinner woman? I try not to judge others on looks, but I suppose when I was at my high weight I didn't feel very good about myself. Therefore, if I was introduced to a thin and in shape woman, I felt that maybe she was judging me or comparing herself and glad she came out on top.
I knew that this was my projection and I think I always maintained an outer friendliness, but inside I felt jealous/bad about my appearance in comparison and didn't necessarily go out of my way to continue a friendship (although I didn't break off any existing friendships based on weight or insecurities). Perhaps what I was feeling on the inside did register on my face despite my efforts.
