Why do some people stop texting you once you dont have a cl with the anymore?

That is weird, but i know what you mean. I have had in cl friends only for communication to stop after the cl ends. Maybe they think there isn't anything for you to talk about/have in common without the cl or they have other things going on. Give it a couple of weeks and try again. If they don't respond, then just move on and find better friends. Their loss if they don't want another friend.
