I really want my boyfriends dog to die so he's sad.
That's terrible. Why would you wish for that?
I want him to suffer like I suffer.
You don't sound like a very nice girlfriend. I still don't understand why you want your boyfriend to suffer for no particular reason.
Because I'm not some weak ass bitch who will break down due to a dog's death.
People love their pets. You have no right to call someone weak over something they find sad. You need some empathy.
