Why did he just stop talking to me?

He 's a selfish jerk. Move on and have a good life without him.

you should of never mention him bringing another girl, or that that would be cool..bc. its not..if he is sleeping with you, why is it okk for him to bring someone else? you are not friends , friends do not sleep with each other, frnds with benefits usually turn out one person being attached. So in the future, don't give a guy an impression that it is ok to sleep with you like its noa big deal, and go out with other girls, he most likely saw not future with you and moved on nd got what he wanted from u..as bad as it sounds.. so let go of him..when you see him don't pay any attention to him...He did you wrong, don't ask him question nothing..that sounds desperate and annoying...if he liked you he would of never took anothr girl..and that txt askin for that girls number was just a hint that he is moving on..and you shuldnt expect anything from him..

I'm not a guy, but I think that he was just using you for sex and wanted to move on after he got it. Sad I know, but that's what it soundslike. He got what he wanted from you and didn't want/need anything else so he didn't want to tell you that to your face, so he just stopped responding. I know it's sad and pitiful, but that's what I think he did. Don't waste your time on him and stop texting him. If he wants to be your friend he will text you himself. Doesn't sound like you lost anyone that great. Move on and find someone who you deserve. He doesn't sound too special to me anyway and there are plenty more friends you can make since you just wanted to be friends.
