advice needed!! 😩

I'm 17 and I've been talking to a guy, he's not my boyfriend but we get along as if he had that title. But I'm not so sure he feels the same about me. I'm not looking for something short term. I wana see where things lead. He doesn't put effort to see me. I am always the one to arrange when we see eachother or hang out . So I stopped to see if he try's at all. And he hasn't . Any advice on other signs I should look for ? 😩
