I'm thinking of pestering my boyfriend about his secret that he has been hiding from me
You are? Why do you want your boyfriend to tell you his secret?
It's not my fault that things aren't going well in my life. I deserve answers
Although you may be curious about the information that your partner is not telling you, it's wrong to pester your partner into disclosing that information. Your partner has a right to privacy and if the information that he has is sensitive and he isn't comfortable sharing, then he should not be compelled into sharing it with you. If things aren't going well in your life, you should talk to your boyfriend about it and get the help and support you need.
I know you are right and I'm going to talk to my boyfriend.
That's good! I hope you two figure out how best to help you.
