Experienced this once. Found out the guy not only held onto his own parachute, but had caught someone else instead and hadn't said so because he "didn't want to hurt me." Glad I broke the bones rather than keep trusting an untrustworthy person.
I think it all started when I stopped liking him. I still loved him, but, I didn't like him anymore. U knew my mind was preparing my heart for that moment - the one I would say 'I'm done' and really meant it.
