how to cut someone you love off!?!?

Amanda
how do you completely cut off your ex boyfriend? he has hurt me but i've countinued to let him stay in my life simply because i am comfortable with him and am in love. but having him still in my life after everything he has done, well it's only made things worse for me. i know it will suck but keeping him around it's not doing me any good. we're okay right now but i need to do this soon. i never had to cut anyone off before so how can i just leave him without no remorse? please help me :(
