While I realize its easier said than done, you have to stop comparing yourself to her. For one, he’s not with her anymore. Apparently all that beauty wasn’t enough to keep him around. Or even better yet, it’s further proof that he’s not solely overtaken by the outer package. That’s not to say that he doesn’t find you attracitve or beautiful or whatever the prefered compliment may be, but I seriously doubt a guy is going to date an uggmug on purpose.
If you want more compliments, perhaps you should tell him that. But you have to make sure not to mention his ex. The minute you bring her into any conversation you start to look like an insecure chick who’s focused on the wrong things. And one thing men do not like is insecure women. Most people have insecurities, but nobody wants to have to deal with them everyday.
You also are going to have to start believing in your self a little bit more. Realize he’s with you. Unless you think he’s cheating, he’s only got eyes for you. He’s not comparing you to his ex, is he? If he’s not, why would you introduce that unnecessary drama into a situation that doesn’t call for it? That’s not fair to you or him.
Just keep in mind: he’s not with her anymore, he’s with you. Stop worrying about somebody he’s not worry about.
