<human>: Crazy significant other stories ahoy!

Mine goes thusly:  I was about three years into a relationship with this girl, high level of trust, respect, etc.  Throughout the entire relationship, one of the things that I always strove to do was to not be controlling or extremely possessive, because we were both people and I wanted her to be able to make her own choices, have her own friends, and live her life the way she wanted. One day she asks me if I mind if she goes to watch walking dead at a (male) friend's house.  I had no reason to distrust the guy, and I had no reason to distrust her, so I told her that, and told her I didn't mind, that I trusted her, and that I wanted her to be able to hang out with her friends.  To me it sounded like a perfectly reasonable answer, if she asked me if I minded then she was obviously ok with the idea, right?  Hooo boy was I wrong, after I told her that she absolutely flipped shit on me, told me that I obviously didn't care about her because I didn't fly into a jealous rage, all sorts of stuff along those lines.  When I explained my reasoning to her it didn't change her mind at all, she just got madder and madder.  This sort of marked the beginning of her descent into crazy, the relationship didn't last long after that.

Give me the gist of the text in a nutshell
<bot>: Told my long-time gf that I trusted her and wanted her to have her own friends, she decided that meant that I didn't love her, shit-flipping ensued.
