firstly thats so pisces sun / aries venus of u lmao, second im confused if u confessed or not cause u said u did and then u didn’t?? but if u didn’t i definitely think u should if he shows signs of interest, with sags it can be kinda obvious (do u know his venus?) im personally a huge fan of pisces and sagittarius, they always remind me of those cute romance indie movies?? even though they have a lot in common (both ruled by jupiter) theyre both kinda flighty and unstable so it seems more of like a fling to me. however i also believe that if 2 ppl love each other sm they can have a long term relationship if they work for it! but ur aries venus will help, aries and sag are very similar in what they want from a relationship but at the same time don’t really have much to learn from each other and grow u kno what i mean?? but this is just based on ur general signs. good luck my dude, sorry this is kinda long
