Im scared im obsessed

Okay me and my boyfriend have almost been going out for a year. At the start of it he was always the one texting me and trying to see me and now roles have switched and I am very obsessed with him. I struggle going a few days without seeing him and if we dont talk much that day i get so upset about it. He also has a best friend who is so obsessed with him and gets angry at him when he is with me just like i get angry with him when he is with him. I love him and i know how annoying i must get but i dont know how to stop and get my mind off it. I try to distract myself as much as i can but it never works. Can someone help me please!!
