Could he care less about me or what?

i'm sure he wants to still be friends with you, but since he has another girl now he doesn't want to talk to you EVERYDAY. he wants to talk to HER everyday. he doesn't seem hurt about the breakup, so it was for the best. I think he didn't date her because he already had you as a girlfriend and maybe wanted to see where it would go. i think he's happy with the other girl and he's not really bothered about the breakup or the after drama that usually comes with it. So be happy for him. It's what you wanted
