coworker dilemma…

Okay this is going to sound really bad but i’ve been working somewhere for the past 2 years. i’ve gotten really close with my coworker lets call him brian. brian is around two years younger then me and i was 18 when i started. me and bria are really close coworkers, we text outside of work all the time and have all these inside jokes. i’ve been in relationships on and off almost the whole time ive known him and although ive always found him kinda attractive i never tried to get with him. our personalities are super simalar, we agree with eachother on almost everything and have always kinda been there for eachother. i’m in a pretty bad relationship right now but i still don’t think it’s right that im thinking about brian in the back of my mind . it’s not like i want to date him but everytime he does all these little things for me or says the things he does it makes me feel a little too special you know? he makes me feel seen and heard like nobody ever has. thing is i know im his type and i feel like he does little things where im like 🤨 thats kinda weird to do for just a coworker friend but i need advice
