It's definitely "the chance" not "the sex." And I'm pretty sure those aren't drug references, it's just referring to the fact that they're calling and they're very emotional. You break up with somebody and then you see that person having a good time and it kinda sucks, you get jealous. "He doesn't want her out there" not because he's scared of her being all alone and getting hurt, but because he's scared of her being all alone and finding someone new.
