He's a drug dealer....

I just found out my boyfriend of 2 years is a drug dealer... idk what to do. I don't want to leave him but I don't want him to do this. He's saying it's how he knows how to get by in life and it's all he's done since he was 9. It really sucks because I know he struggled during his childhood and the "streets" is all he knows but I think it's time he grows up and stops letting the "streets" raise him. Idk what to do I love him so much but I FUCKING HATE DRUGS....
