I need to stop stalking my boyfriends ex, please help? (10 points)?

[angel..x]

Lets calls her emma, we look completely opposite. She has boyish cut ginger hair (dyes it blonde) and blue eyes. I have long curly black hair and brown eyes.
Emma and my boyfriend went out for either a year and a half or two years and they broke up because she cheated on him and slept with another guy. Tbh, she's cheated on most of her boyfriends. My boyfriend doesn't love her anymore I'm sure, besides they broke up three years ago. I guess I'm really insecure about myself but my boyfriend always reminds me I'm beautiful and everything else. His amazing . We've been together about a year and he asked me out 2 years ago but I said no because I didn't fancy him.
Anyway, I'm always stalking Emma's twitter and Facebook. She has a boyfriend and has gad several ever since they broke up but I'm so insecure I guess I just compare myself to her. Everyone says I'm a lot more attractive and 'natural' because I don't do the whole dying my hair and fake tanning all the time to the point I'm slightly orange. I sound psycho but I really can't help it. Im also a virgin and my boyfriend lost his to her which really tears me up but in the past he did say he regrets it. He is very serious about me, his friends and family know about me and he treats me so well. Please can someone seriously help? It's making me feel so ugly.
