Boy Problems Someone Help Me. Asap?!

Okay i'm going to make this kinda long so sorry if that bothers you but I need help so yeah. I really like this kid named Justin. He has a girlfriend though and his girlfriend is my best friend actually. But the thing is that Justin and (Nicole his girlfriend) have never met. One of my good friends his name's Timmy and I called him one day just to say hey and stuff and his friend Justin and my friend Nicole like got hooked up somehow and i didn't really like him but now i do because i've actually like met him and stuff. Before he asked out nicole i had told him that me and Nicole were going swiming and Justin asked me if i was wearing a pink bikini i don't know why really. But i met him like yesterday and I feel that he doesn't even like me that much he think's i'm all like girlyish i mean he didn't tell me that but he's just like "wow why do you like to shop alot?" I'm confsed because me and Nicole are like the same people pretty much. We say the same things, Shop at the same places and pretty much like the same guys. But Justin likes to shop at Zumiez and stuff. Then his bestfriend Timmy likes me but i don't like him back because i like Justin but he doesn't know it. So yeah. Lke yesterday Justin text's me and he's all like "When I see Nicole should i give her a hug?" and I'm like "Yeah! go for it! For sure!" and stuff like that even though it really hurts inside. I seriously wish he liked me.
