I wish my boyfriend was dead
Why do you want your boyfriend dead? Do you have a reason?
Yes, he sickens me due to his personality
I understand that you might not have romantic feelings for your boyfriend anymore, but it is wrong to wish for bad things to happen to others, especially something so severe as death. You should just break up with your boyfriend if his personality bothers you that much.
Thanks for the insight but I think it is fine for me to wish for his death.
If you dislike your boyfriend, you should break up with him. It isn't good to wish death on him because you don't like him.
