It sounds like he isn’t interested. If you know him in real life and not online, for example through school, then talk to him about your friendship. Or just send one text asking if this is the end of your friendship. But if he doesn’t reply or give you a straight answer, you should block him and just move on with your life. It doesn’t matter how much you like or love him. Give time to those who will spend time for or with you. Good luck ! ❤️
