Calling the cops on your girlfriend because she won't leave is a pretty bitch move, and throwing earrings at her from the window is fay as fuck. I also don't believe the cops would cart you away without a reason and Kyle either told them she was crazy or they were both blubbering wrecks. On the other hand, nothing in this is particularly damning. She's drastically overblowing this and is freaking out over relatively nothing. pro tip, if you don't want to get locked up, don't mutter 'don't lock me up' to yourself. She got PTSD from a basic psych eval. Spending a few days in an actual ward isn't that bad as long as you're not criminally insane. I don't believe for a second she's been freaking out about this for 5 fucking years, and if she is that's her fault more than Kyle's.
