Super exhausted. Totally have developed an obsession/attachment to my coworker. I have a long term boyfriend so this is a frustrating theme to handle lol

i recently about six days ago ? started talking with someone with the intention of being friends and we’d talk a couple of times a day every for the past six days. But i immediately grew incredibly attached and obsessed with them i have no idea why it’s been driving me crayz. it didn’t help when they teased (?) me i guess and said if my compliments or well praise to soemthing they had done was flirting. it hasn’t left my mind at all. i don’t know what to do or why i’m feeling like this. and the worst part is i can’t say anything to them because i’ll just look weird i bet. i can’t help it i think about them so much and i check their stuff a lot and my lockscreen so much to see if they’ve texted me… is there any way to help with this ? it’s been really draining and causing me to overthink really badly.

False attraction has been killing me ive had it for months with the same person. I have a boyfriend so having false attraction makes me feel so guilty. And lately theyve felt so real and ive been so anxious. What if I do like him bla bla. Ive only ever saw him as a brother and we have a good connection and he is one of my good friends but even sometimes when im having a conversation I feel like im cheating. Sometimes I get excited like oh yay he is gonna be here and then I get scared that it’s romantical because I get excited when he is around because he is a funny. Im so scared thats its real attraction because I love my boyfriend I would never do such a thing. And lately my minds done stuff like oh grab his attention stuff like that and it feels like I have done those actions but I dont want to. Sometimes when he is like idk sitting near Im like oh is he looking and my minds like oh do something to empress him bla bla. Recently he was going thought stuff and my boyfriend was there and I was I can give him a hug because I think he needs it but after I thought of it as bad because he is a guy and I had this false attraction what if I did it because I like him bla bla. I am freaking out idk why my mind makes me do compulsions that I have acted on like oh go talk to him and I do its weird urges that I do not want to do. I am scared that it will come true

any help is really welcomed and appreciated. I tend to hyper fixate on men outside of my relationship, they feel like crushes but I’m like 60% sure they’re meaningless dopamine rushes that happen with people I find interesting, friendship worthy, or physically appealing in some way. My hyperfixation recently shifted to a supervisor, not even an hour after meeting him :/ that’s fine, whatever, I can’t do much about it. I daydream and create like this drama romance in my head. Like good content for a movie or a book. Comparing it to that makes me feel less disloyal, and more understanding of why this might happen (I am a hopeless romantic, I adore stories). I’m home now and I was thinking of wearing a cuter shirt for work tomorrow because I went in an oversized hoodie today. This is a thought I had this morning before even meeting this man btw. But then my brain went to oh yeah I want to look attractive for this hyper fixation. It felt exciting to think that. I felt excited. Then the huge wave of dread hit me. I wanted to look good for another man? For a specific person? I can’t stop panicking I don’t know if this is normal, disloyal, a distortion, or what it is. I’m so confused. I felt happy when I got that thought. Maybe it was a dopamine hit or something I’m Colombian and we’re really big on looking our best 99.9% of the time. Even if it’s just to go to the gas station. I just feel so scared that I felt excitement over this one person. It’s extremely different for my boyfriend’s culture. Almost the opposite. I feel so disloyal and unworthy of my boyfriend. I doubt this was intrusive, it genuinely felt like me and I’ve had thoughts like that in the past. I just feel like a huge monster right now Please help :(
