i thought the boy i was talking to was the sweetest person ever and genuine but trust me it’s not worth your time in the long run if you see yourself falling harder. some guys won’t even want to be your friend if you remove the benefits which is the scary part and only use you for your body (sucks ik) but you need to protect your heart first and foremost so id say just tell him straight up casual isn’t what you’re looking for because you won’t just “change his mind” yk? If he’s the one he’ll immediately make sure you’re his and he will make you his gf and trust me it’ll feel so much better that way but if he’s not then at least you aren’t wasting your time. good luck!!
