Why is texting so important? I have things to do during the course of my days, and sitting around wasting time texting isn't one of them. Maybe your boyfriend just doesn't feel like it?
Usually, when people first start seeing someone, there might be a lot of texting, but then that dies down. Because it's a big, fat waste of time.
If you want to talk with someone, then call them and talk with your voice. Or don't have sex with them if you're a bitchy person. Whatever works for you, i guess.
