Can I ask you how old you are?

I'm just curious... I'm in my 30's and I have a friend who is in his 20's. He thinks its perfectly OK to have a text conversation where we are going back and forth steadily, and then just disappear without another word. I think its rude because the context of a conversation has been set and you wouldn't walk away from any other conversation without saying something, but he says its ok to just stop texting whenever because "its only texting" and therefore not important or urgent.

But, I'm with you. I think its unacceptable to be having a text conversation and then just stop responding without saying "gotta go" or something like that. I think its basic courtesy. (Then again, I know I'm in the minority of people who's parents sent her to etiquette classes as a child!)

I'm not sure how to handle the situation as I never fixed the problem with my friend.

In terms of misunderstandings, maybe its best to keep texting light and only talk about problems on the phone. She has a baby....but really this is her own doing as she cannot handle a text conversation without seemingly pouting and rudely walking away.
