You say that on this site, of all places. You're argument would only hold up if the person telling the other to drink bleach cornered to other, prevented them from escaping and pushed them into it. Otherwise the other has the option to walk away and deal, and most people do because they are not weak willed babies who would jump off a cliff if you told them, no matter how you see depression.
I don't think you seem to respect people are rational adults capable of making their own decisions.
If someone here says drink bleach, it's assholish, but you can log off and walk away. Maybe complain to family or therapist, but you're not cornered or forced into it. Same with your ex, she's not cornering or forcing you to be miserable. She isn't stopping you from going out and enjoying life or working. She isn't calling you everyday telling you to be miserable even if you change numbers.
She isn't out to make you miserable, any more than the lamb is out to make a lion hungry. You think lamb wants lion to be hungry, to suffer? It just doesn't want to be eaten by predator. If lion was happy and full lamb would be happy. If it could make lion not want to eat it it would. But stupid lion blames lamb for making it hungry and running away, what do you expect? You're too busy thinking how YOU feel without thinking how others, how selfish
But hey if you think saying "drink bleach" is so horrendous there's a whole website here we're you can speak to half the users who say just that and preach how wrong it is. But you don't bother if it happens to some other lolcow, do you? hypocrite. Just that you're salty and how you alone feel. You're so wrapped up in your own minuscule world thinking about your feelings you don't give a shit that others have a right to their own lives.
