Soo I like this guy who has a gf and we are friends since we work together, but idk if he’s flirting with me because every time he sees me at work he always signals me to come over for a bit and we talk for a bit. Sometimes we fool around especially him. Sometimes he touches the back of my head, or slightly pushes me, he makes me laugh and smile every time i can’t help he makes my day better. I just want to know if he’s flirting or not :( because If he is I want to tell him to stop since he has a gf.
