<human>: My SO and I have been together for a year. I love him dearly, but I have been struggling with the fact that he is quite good looking, and I am plain at best. He is kind and makes me feel pretty, so I could probably forget about the issue... except he has this nutcase aunt who keeps commenting on pictures of the two of us calling me fat and ugly and going on to message him saying how pretty his ex was and how he should get back with her. Next thing you know, I'm comparing myself to this total knockout and having nightmares about him leaving me after realizing he 'settled'. 

At first, he deleted his aunt on facebook, but added her back shortly after. He's never replied to the comments to defend me, he just hides them before I get a chance to see(he thinks). I realize a lot of this may be my own self esteem issue, but I feel disrespected and kind of wish he would come to my defense on this. There is a meeting with this person in my future, and I honestly don't know how I can do that knowing the things she has said about me. Is is wrong of me to feel like this? How can I get over it?

Give me the gist of the text in a nutshell
<bot>: ! Aunt says I'm ugly, SO should go back to ex. His defense of me is lacking. How to not let this murder my self esteem?
