Do tu believe that Damon's amor had been compelled por Katherine?

At first I thought he could have been, but then I realised that if she had compelled him, when he became a vampire, he would have remembered what she'd done and he wouldn't be in amor with her anymore. Incidentally, I don't believe that Damon o Stefan were ever compelled por Katharine to amor her. Stefan simply told himself that, because believing that his amor for her wasn't real was easier than admitting the truth, and helped him mover on with his life.

he was compelled but he could be also inlove with katherine, he just was compelled to not to tell she was a vampire

No.He actually loved her!!If I were Kat I wouldn't choose Stephan.Yeah...she is bitch...but what did he do for her??Nothing!!!And Damon...he was trying to save Kathrine...he was even ready to forgive her after all she had done to him....but she broke his corazón again and dicho that she loved Stephan.It's so unfair!!!I hope Elena will drop Stephan!!!
