I need help!!! (the problem's under details)?

I'm in eighth grade. Last year me and my friends Taylor & Sanaya were best friends. Over the summer this girl Kris and her twin brother Daniel(also in eighth) moved into Taylor's neighborhood. Now Kris, Taylor, Sanaya, and me are all BFFs, and I like Daniel, so does Sanaya. It was fine for a while but Sanayas a physical person so when she saw we reading her texts from Daniel on the bus she scratched me and i started bleeding. We read each others texts all the time so for us its normal. The texts said from Daniel, I nvr said i liked u and some other stuff. So i kinda got mad cause shes always saying that she doesn't like him and obviously she does. This was all yesterday. I talked to Daniel about and he said he liked me. I go over to his house and sleepover there alot with his sister while hes there cause he asks me to. (we don't do anything baad). We just kinda flirt and he plays with my hair. So then today Sanaya was like oh daniel said that he likes this other girl Katie, shes a popular, anorexic, stewpid, $lut. she really is. im not being bias or anything.I asked him and he was like oh ya i do. So i got kind of mad and told him i hated him. he asked me why and i wouldn't tell him so i finally stopped texting him. What should i do?? (thank you so so so much for the help, i know this is a long paragraph.)
