As far as 180s, she stopped saying I love you, avoided conversations about us, was cordial not argumentative, laid low by not being too busy with me via texts/calls, never asked how she looked or if noticed changes, she was very nuetral.. Thats all I can think of right now that is in the 180 list.. But she did GAL, and moved on..
These sound more like falling out of love and indifference than 180s, imo.
180s are like you always used to argue and debate her logically and instead you now listen and validate. Or you drank way too much and were an alcoholic so you decide to stop drinking. Or you got really out of shape and all of a sudden you hit the gym and get healthy.
