HOW do you break up with someone emotionally unstable?

Straight up, you're not going to break up with him without him using drugs afterward. Know that. That's what happens when your addicted to drugs. Cold truth lady. I'm not saying it's your fault, he probably will mind you... But the only thing your guilty of is being a dummy. Your junkie boyfriend did drugs before you met him and will do drugs after you dump him. That shouldn't be a newsflash.
