Did i make another mistake?

ok so there's this girl when i was in school because its summer right now, and when she first got to my school there was drama that she was involved in right away. after the drama died down, she was best friends with and only hung out with these other 2 girls and the three of them always got in trouble in 1st period P.E.and then apparently those three had their own drama and weren't friends anymore then 1 of them moved away. the remaining two stayed away from each other but for the rest of the year i always heard that she spread rumors or always kept them going from my closes friends that hung out with her regularly. as school came to an end me and her began to talk more and more and then she started to come over a little. we were really close the last week of school and she hasn't stopped coming to my house. two days ago i called one of my close friends and we lingered to the subject of that friend. we were talking about how aggravating she can be and we have the exact same complaints. every time she comes over she always wants to go somewhere else. she always pressures me to ask my parents to take us somewhere or to give us money to go to the store right next to my house or other places. another thing is she just recently got the newest droid and that is all she's into when shes with me. my biggest complaint is that she NEVER brings her own clothes when she spends the night at my house. if we go somewhere she changes into my clothes and she changes into my stuff alot. jackets, socks, shoes, sweaters, underwear,shirts, and the little bit of make up that i have even thou she wears and has much more make up than me. the last time she came she didn't even bring shoes because she said she wanted to wear mine since there cuter than hers but the week before she said she went shopping and had on all new stuff which she practically rubbed in my face. and i mean accessories and vans too. my other friend i talked to on the phone said she never brought clothes the times she pent the night at her house either and told her dad that she would just borrow their stuff when he said he would drop some clothes for her. despite all of that i have opened up to her little by little every time she visits and feel guilty because i feel i shouldnt trust her like that. should i tell her about the clothes and not tell her anything anymore? PS: sorry this is long
