HELP 😩

Okay, so this is going to sound super dumb... but there’s this boy that I’ve been eyeing for awhile & we have a streak on snap and he’s flirted with me a couple times, but he’s never gone farther than calling me cute and then ending it there. I would start conversation myself and try to get things to move, but I’m so freaking shy and hate going outside my comfort zone, so I just don’t know what to do. Please put some tips, I’m literally desperate.
