Is this girl mean or am i just weird?

there's this girl that ive known since the 7th grade well i think shes kinda mean but nobody else does so i find that kind of weird.. well when i spent the night at her house i forgot my pj pants and instead of letting me borrow a pair of hers she made me sleep in my jeans...shes really mean to her boyfriend like she doesn't even kiss him and when he talks to her she ignores him they've been dating a year and they haven't even gotten ped a simple kiss...for valentines day he made her something and she threw it away she didn't even make him anything. whenever someone asks her for something she always says no like i asked her for a sour patch kid and she said no even though she had a whole bag and even if you ask her if you can use her pencils she still says no.. oh and also when i spent the night at her house she made me sit there and do what she wanted and even though i didnt want to do it i had to sit there and watch her do it
