I cant seem to get past her comment about my weight?

[Barnes66]

This girl from work embarrassed me in front of other co workers by pointing that i had gained allot of weight.

When I saw her next time I told her that I was hurt by her comment and she acted all surprised and tell me why I didn't tell her that at the spot.Then she said sorry.I suspect she was just playing stupid

anyways, I used to be very friendly towards her and we would talk all the time but now I go out of my way to avoid her. I don't say hi first but I do respond whenever she says hi and that's about it. I don't feel comfortable around her and the vibe and energy I felt towards her just not there anymore.
I go out of my way to sit on different table in the lunch room and I don`t sit with her like before and talk to her.
Its been a year and I have lost weight again but I don't feel the same way towards her and I now truly dislike her. sometimes I think to myself to put it behind me and give her the benefit of the doubt but just don't like her anymore. She always smiles and say hi to and I know she is trying but its just not there anymore. I say back but its forced and doesn't feel natural. :(

Is it normal to start disliking someone after they offended you. Is it defense mechanism

she showed her true colours and you responded. Her apology sounded false, there is no way she didn't realise what a hurtful thing she said.

I do think it's time to put the comment behind you, but that doesn't mean you need to be friends.

I don't understand how some people find it appropriate to comment on other peoples weight. Good on you for losing the weight! When I had my dd I visited my work place around 2 weeks after. One of my moron colleagues who has said impolite things to me before said "you wouldn't know she's had the baby!"
One of my more sensible, who had actually had her baby herself, reminded her it was only two weeks ago that I had given birth.
