am i just weird or is everyone else also like me pls lmk lmk

ok basically its like when i like a guy or even when i have a friend thats really special to me, i get really weird about them having other friends or other people to talk to i just want them all to myself. its not even that im insecure that they'll cheat or leave me, i just want to be as special to them like they're special to me and i feel like i hear so many guys say they like jealous girls but the same guys constantly push me away, and even when they don't push me away, i start to push them away cus i feel uncomfortable?? 😭 idk its weird but im sure at least some ppl act like this too
