Girlfriend And I On Break, Be There For Her?

Me and my girlfriend are on break, her choice not mine, but we are also best friends in ever way and we both love each other more then anything, and I really mean that its not a silly high school relationship this is real, we've both felt it. I know I should go with the break and go check out other people w.e all that, but when she calls crying about something I want to be there for her and I still call her sweetie and all those things but I don't know I think I'm doing this wrong but it pains too much to not call her "sweetie" (reserved for each other regardless of other relationships) or not to comfort her when she's sad. I say I love you well not even that.... Its not only me she says it to, I won't usually say I first, she will... And when we see each other sometimes just maybe just out of habit, but w.e it is we've kissed and hugged.... Especially when either of us are feeling down... We've been on break for a little more then a month now but it still pains and I get jealous when she tells me that she cuddled or something with someone else, its really hard to be on full break.... We've been getting better at though but I just need her to look at me the way she did before, which she does when we're out of school but her friends screw things up so much because they don't believe in talking to your ex- or being friend with an ex- or anything of the such on top of hating me... I just don't know what to do I feel down and.. I need to talk to her.... Cause not because she's my sweetie but because she really is my best friends and feelings like that I just don't feeling comfortable confiding to anyone else.... And I believe she feels the same way its just so confusing... I just wish I could have her back finally..... Or at least know where be boundaries should be to be able to get her back
