advice..

ok so im best friends with this guy. we do flirt a lot with each other but that only lasts a few days🤦🏼‍♀️ i would love it if he liked me back:/ he calls me his future wife and all that. we’ve always been each others number 1 bffs on snap. we have even sent “pics” ( haha😉) to each other. the problem is i know he sends stuff like that to other girls... i tell him to stop in a joking way because i dont want him to get exposed or anything like that. i just dont want to lose him in the friend aspect of things if nothing works out 🙁 its not fun but i do enjoy it some days! recently ive started talking to this new guy though. the flirting between dude #1 and I has stopped. dont get me wrong dude #2 is amazing and deserves the world but i still think about dude #1 a lot. then just yesterday dude #1 asked if we could hang out and go to the movies and all that. we’ve made plans before and they never happened and i told him that but he said he actually wanted to. i want to sooooo bad but dude #2 might not appreciate that. dude #2 is falling really hard for me and he’s soooo sweet, just not for me :(. i know, i should end things immediately with dude #2 but its complicated, i cant just say “we’re done” 🤦🏼‍♀️ any advice ?
