I told a girl I needed to talk to her through texting but she kindof blew me off, did I ruin my chances to ask her out?

Could be. Different women have different preferences. But if you want to get to know her better texting is probably not the best way to do it. You might try actually speaking with her.
Is this the venue? This doesn't really sound like a medical question. Perhaps you should try posting it on DatingTap.
