Dear ,
You're such an unappreciative, manipluative brat. She's not obliged to listen to everything you ask her to do, you're lucky she's as sweet as she is and that she likes you as much as she does. You have such a sweet and sympathetic girlfriend and you're using her to do your work and make your ex-girlfriend jealous. Your intentions were very clear and I'm certainly not the only one whose noticed. I don't know why she is staying with you or what sees in you but she wont be there forever. There are absolutely no benefits to dating you and I hope she realizes that much. Also, your exgirlfriend is smart enough to understand what you're trying to do and she doesn't appreciate it.
