I hope I don't get any hate for this but I feel bad for both...she keeps saying he treats her like trash when instead he'd always tried his best to make her feel better throughout their childhood. They're both in the wrong,so it kind of rubs me the wrong way when she puts all the blame on him without trying to consider how he might be feeling. He said he's scared of breaking up one day(which is an understandable fear),so that's why he wants to stay friends,but she's treating him colder than when they actually were friends.
They're definitely both in the wrong in certain instances, and she's also sometimes taking his feelings for granted...
