Should I ask my best friend if he still wants to be friends?

I've been through the same thing . But sadly , I cut it off with my best friend . I never talked to him again & I miss him every day . Also , I feel non-stop regret . Please , don't stop talking to him . Just keep making an effort . He'll come through some day . Or , you could always just send him a message . Just be like "Hello , we haven't talked in awhile . Is there something wrong ? You can tell me anything ." It sounds to me like maybe their's something going on in his life , & at the moment he feels as though he doesn't have time for friends . He really does , he just needs to be pushed a little . Keep trying .
