i’m sad

i’m really sad and i have a feeling it’s because the guy i’m interested in and i aren’t talking. i’m literally obsessed (not really) but sometimes he really takes a toll on how i feel. it’s just stupid things like if he doesn’t hit me up or if we are talking and he just doesn’t seem interested. some times we’ll have a really good convo and he’ll take control of it and others he just gives one word responses. i know he doesn’t have feelings for me too, well i don’t know but i think. i’m too shy to tell him i have feelings for him and i don’t wanna hit him up because i feel like i have for the last couple days. he’s also really confusing... like he told me he doesn’t wanna date anyone at the moment (it was completely random!) and then he was talking about how he was sad cause he was single. other times he asks me about my past relationships and it’s really random and it makes me wonder ya know? but it’s just me overthinking i’m like 99.9 percent sure. part of me thinks that if he wanted me he’d say something and the other part is like well i want him too but i’m not saying anything. can i get some of your opinions and though on this?
