obsessed ex boyfriend
a guy who can't live without you. He texts you so much he gets a second phone. He stalks you online. He even tried to break up my relationship with my girlfriend just so he could have a new victim.
'I'm going to die if you don't reply.'
'You broke me. I tried to kill myself. It was your fault.'
'If you don't call me back, I'm going to follow you to work.'
