How long would a girl wait to text a guy back if he stops texting for days?

Let me start off by saying that I'm a 27 year old woman so things may be different with age and maturity. If a guy stopped texting me, I don't text him back. No waiting period. I am grown and have a career and bills to pay. I don't play games. Either you want to talk or you don't. However, I also don't let the guy do all the talking either if I'm interested in him. A good conversation should be 50/50. If a woman isn't putting forth some effort in the conversation then she's either not that interested or it could mean she's really shy. I'm betting more on the first.
