do i let him go?

so i assume everyone has heard the quote “if you love someone then let them go and if they love you they’ll come back” and i can’t tell if this applies to my situation or not. basically i liked the boy and we hung out a few times, we definitely kept it low key, but anyways i thought it would be a good idea to start being friends w his friends(he was friends w mine). but then after a month of snapping and talking to his friends, it started to feel like one of his friends started to be my friend too. at this point i had been hanging and “talking” to this boy for almost 6 months and his friend about one month. his friend was giving me advice on him and telling me things like “i don’t think he’s that into you” and “i know him he’s probably talking to 20 other girls rn”. i started doubting our relationship and second guessing everything. then the guy i liked started getting a little distant and i started getting really confused and confiding in his friend, who was telling me to get out before i got hurt. then i ended up finding out that his friend liked me. and i got r

rally confused, i started asking myself which one i really liked. flash forward to now (this all happened around November) i’m still hung up on the first boy i completely hate his friends, for lots of things but basically he’s an ass. in the last month i started getting over the original boy until out of the blue he texted me and then we didn’t talk and i started getting back to being over him and then he texted me again. this time i went off on him basically asking what he wants and spilling my guts out to him, because he has a gf and i’m always the one left alone and broken. i also put a really cute picture on my private story for valentine’s day and he slid up and said “no”. when i asked him why he said no he just said “i don’t know” and then he said “just no ya know?”. basically i need someone to help me do i wait for him to figure it out even though he has a gf or no?
