@mollylondon1373,
First off, I don't have any idea why you have not heard from him. Heck, maybe his phone got destroyed and he has not yet replaced it. Or maybe he fell head over heels in love with a real live woman that he, you know, physically met? Someone mentioned trying to call him if you have his number. That would be a perfect way to find out what is going on. Certainly better than coming on A2K and asking us what is going on.
I will never understand how anyone, male or female, attempts to develop a relationship through texting. That little device that you use to send these texts to each other can also be used as what us old folks call a telephone. You punch some numbers and it will ring on his end, letting him know to hit a button and hold the device up to his ear. You hold your device up to your ear and lo and behold, the two of you can actually speak to each other over long distances. It is called a conversation and is much better at developing and enriching a relationship than texting.
