she know herself well, but she never admit it

she's a letting go person, but she never admit it. she's hard to make a friend, she's bad at starting conversation and she's not good at keeping friends. I know exactly that her friend don't ever think to leave her, but she act like she will be okay without them even actually she's not. I don't know what's on her mind, I dont know what's inside her brain, she's insane. even with her love one, her love one never ever think about leaving her, but she -just like what I've said- not good at keeping friends, and keeping her love one. so, she act like she will be okay without him, then she let her love one go and leave her even she's not ready yet to be leave. I know what she feel and so does she.
