Best friends. HELP!! emotions too?

Ok so I no this Bf of mi e is going thro a tough time and she is the kind of girl who cries once every blue moon. I want her to no that it's ok to show emotion and talk to me about her feelings, cuz I no there there. Once wehad a sleepover and wetalked all night about our feelings and I could tell I was letting her guard down and breaking her wall but we fell asleep. I'm seeing her soon and want to no how to get her to open up. Here's tha thing I looove comforting ppl and listing to their problems idk y. I dont wannna say just take to me or something bc it just would b awkward. She has gotten into boys and texting more too. Were both 13 but in preschool she got to go to school before me so she's in 8 th grade. I just want to make her feel like I'm there for her to talk to.
