@Jessiejohns1217,
I am going to operate under the assumption that you're teens in high school.
Crushes come and go. Friendships can last. In the meantime, though, you're a little too involved in his personal business. Yes, you are close friends, but it feels like the two-seater car of their relationship is crammed with extra people. Also, the 'secret relationship' junk is for the birds. If his folks don't approve, then he's going to need to deal with them at some point, and also own up to the fact that, guess what, he's lying to them.
You so sure you want to be a part of this drama?
Here's an idea. Make other friends. Male, female, whoever. Spend time with other people and extricate yourself from this stuff. Yes, you care. That's nice. But (1) he didn't choose you, (2) he's lying to his folks, and (3) he's unfairly involving you in his own personal junk.
