Codependency or normal? F20 M21

So I’ve been having some major issues recently. I can’t seem to think of anything other than my boyfriend. Anytime I’m watching anything or doing an activity my brain just thinks of a million ways that it relates to him. And if I’m not doing that then I’m zoning out every 15 seconds thinking of him and I often have to rewind what I’m watching because I’ll be so out of it. When he’s not texting me, I feel abandoned, and I feel like he’s on the other side of the phone seeing my text, and ignoring it because he hates me, when in reality we’ve been together for 2 1/2 years and I know he loves me dearly. The second he responds all the bad thoughts go away but when they’re there, they’re SO strong. I feel like I don’t have anything but him and anytime he’s goes out with his friends or family, I get jealous, and I feel as if I shouldn’t text him at all because I know I’ll just put him in a bad mood if I make it about myself. (Who wouldn’t be in a bad mood after that??) But I can’t help feeling jealous!! I try to ignore it. I just feel like everyone else in his life has things to offer him and right now I don’t have anything other than conversations to offer. He doesn’t let me buy him gifts and when I have he gets upset and says he wished I saved my money instead. I’ve tried googling what to do and it just keeps telling me to focus on self care or talk to friends more but I don’t have any friends and I already take care of myself. I spend immense amounts of time making sure I’m properly groomed and clean. It’s often what I do when he’s not answering. I’ll take a shower or clean my room. I physically feel sick when he’s away from me. I just love him with all of my being. Like every fiber in my body just yearns for this man I want to cook for him and have his children and clean for him and always be there to support him. But I’m worried that this isn’t normal. It feels way too strong and I always come off as overbearing and I constantly feel like I care more about him than he does about me. He does everything for me and he’s always so kind. I don’t know why I feel like this. I don’t like being alone with my thoughts I just always want to be talking to him and it seems like he doesn’t want to talk to me when in reality he just has his own life and stuff going on. And for some reason my life and stuff going on isn’t enough to distract me from constantly thinking about him and talking about him and checking my phone to see if he’s replied. Is it codependency or am I just clingy and this is normal?
