I'm hoping my boyfriend will fail. Does that make me a bad person?
Why would you hope he'd fail?
I want to have an excuse to break up with him and see other people.
If you are in a relationship, you should be supportive of your partner and want them to succeed. If you do not, then you should break up with them so you can both find someone you love. Don't wait for him to fail at something to break up, just be honest with him and do it right away.
What if he won't listen to me?
Waiting for him to fail would be a bad way to end it. It's mean to hope for something like that on another person.
