Jealous or not?

I got accused of being "jealous" of my boyfriends fat ex. There is a difference between feeling jealous and feeling disrespected. I felt disrespected as I am his current girlfriend and I keep seeing his ex's name on his stuff (Amazon account, Microsoft), at a takeout place and today when we went to pandora. She literally plastered her name on lots of his stuff. She might as well still be coming over. It makes me feel desperate to tolerate his ex's name on his stuff around the place. I mean, she's fat with an ugly face so it puts my self esteem down. Wish she was pretty at least. Do you think calling me jealous was ok?
