Help please lying at MEPS?

I just went to MEPS for processing for the USAF. I swore in and now I am in the DEP program. When I was 13 I was getting into trouble. I got got arrested for a domestic violence but I never was charged with it. I was fingerprinted for it. The main charge I had was a retail theft when I was 13 the item was like 15 dollars which doesn't need a waiver because it's under 50 dollars. That led to me being on probation. I kept violating my probation so I had to go to the jdc form anywhere like 2 weeks to 3months over the course of 4years. I also had to go to the juvenile DOC, because I kept violating my probation by skipping school and missing curfew. Nothing serious but the judge was getting sick of me. When I was 16 I completed a Military school and got off probation at 16. My record was sealed and closed. I told my recruiter about the retail theft at 13 and about the violation of probation, but my recruiter told me to lie and say that I just had a retail theft and I completed my probation and it's closed. I didn't mention the other things to him because he told me that I would need a waiver and now you have to score a 65 to get in the USAF with a waiver. I have been trying to get in for the past 5months and I would have to wait even longer if i get a wavier. I was 4 points away from 65. I don't know what to do. My recruiter said I it wouldn't show up and that when you a juvenile petty charges like that don't matter(the retail theft). I am now 20 years old and married my husband is in the airforce. I am no longer like I was when I was a young teen.Will they find out? And will I get kicked out of the military if I leave for basic? Please help! what should I do?
