I hate this guy so much. Plus...?

[Jewls]

When she called you being too self-critical, did you hear the tone of her voice? As in was she serious or joking?
And I know what you mean. You have a frenemy. He's just too conceited, narcissistic, and self-centered right? Always trying to bring you down? He wants attention to make himself feel better.
If she's not into you, she's not into you. Maybe she wants guys to fight over her. Don't do it. Maybe once she sees you're not giving her attention, she'll want to talk to you more. You should get over it because you'll have to please her all the time. If she's not wanting to talk to you and doesn't start the conversation with you. Honestly, who wants someone that's egotistical.
