Why would you ever be excited to be with someone who is not excited to be with you? If they’re not happy with you now, what makes you think they’ll be happy to be with you later? Why do you make an effort to convince someone to date you when they make no effort to convince you?
What does that say about you? That you believe you need to convince people to be with you?
You wouldn’t buy a dog that bites you all the time. And you wouldn’t be friends with someone who regularly ditches you. You wouldn’t work a job that doesn’t pay you. Then why the hell are you trying to make a girlfriend out of a woman who doesn’t want to date you? Where’s your self-respect?
