It's easy to overvalue girls in the 8-to-10 range. You're probably just fine swooping them in the beginning because you figure "what do I have to lose?" by trying. Then, once you've gotten a week or two in, you start caring too much about outcome and they're picking up on some sort of needy/clingy vibe. Without knowing you, I can't say for sure this is something you're doing, but it's something to be mindful of.
I'd recommend keeping your text game mostly logistical, especially before getting the bang. Don't just text for the sake of texting. If you MUST text her, have a specific reason for doing so and don't drag it out too long or you'll kill the mystery surrounding yourself. Dates are the proper venue to build rapport/close. Remember, the game is won in the field, not over the phone.
