I know a lot of people overthink when they start to like someone, but I feel like it's getting really unhealthy for me mentally. He made it clear through his actions that he is interested in me. For example, he gets jealous when I talk to other guys, he's always next to me when we hang out with our friends, and we've had our magical moments where we would look at the stars together when we're outside. I know that he likes me, but I keep overthinking and I'm continuously convincing myself that he doesn't like me and that he finds me annoying. I have tried to stop thinking about him and just focus on myself, but it hasn't been working. Do you guys have any tips or advice on what to do to shift my attention from him?
