If my boyfriend goes to jail would it be fair if he told me ro wait for him?

My boyfriend isnt a criminal it has something to do with a driving accident but he clarified that he may go to jail for 5 years cause it may have been his fault. Were both young. Hes 17 & im 16. I love him dearly & it would kill me iff ge did go to jail cause i would feel it was my fault. Do to the fact he was talking to me. He asked me iff i would wait & i said yes. He asked me again cause in the past i made a mistake & cheated but i was truely sorry & am ready to commit. Should i wait? Please help
