Crush ki girl best friend he🙂

So mereko is ladke pe crush tha and he seemed really nice and genuine person....kabhi kabar eye contacts bhi ho liya karte the....aur bande ka meme page bhi he so he funny and all...looks wise bhi decent lekin abhi abhi pata chala ki vo apne circle me ek ladki se bohot jyaada close he(the girl is dating someone else , she is way out of her boyfriend's league). Like really close, at times they play hit each other while her boyfriend's sitting by her side watching and this doesn't feels right....like wtf....and you could literally see them together everywhere and now I get to know ki he said that he thinks I am cute(we use to make eye contacts and all so yeah). But I don't really like how their friendship is....what do I do????
