Do you ever wish you didn't love your SO?

Have you ever been pushed to your breaking point time and time again by the person you loved so much that you wished you didn't love them so you could leave, and never put up with it again? Did you ever know you weren't being treated right, but any time you tried to end it you couldn't because being without them broke your heart more than the pain they were causing you? If so, what did you do to get through it?
