Is this cheating ???

- I love my boyfriend to death . He is my future and definitely see a marriage with him.

My co worker form work is really funny and we were taking over it dm one day, we dont flirt like he's never complimented me or said I'm pretty or anything, the nicest thing he said to me is " happy new year hope it's as great as you "

He's a year younger than me and I'd never do anything with him I see him like a brother

He's so funny and we always make work jokes and like this one joke about where everyone goes ( like a destination)

We dont talk anymore I kinda cut it out our convos were getting pointless and he left me on "seen"

Long story short is me taking to him considered cheating ??

Like I never would do anything to upset bf so I just feel guilty
