Affiliate Marketing Secrets

Hi, we’ve been thinking about getting term life insurance and finally decided to move ahead with it. I talked with the agent (not affiliated with any one insurance company but deals with policies from a few companies), who, over the phone completed most of the application and arranged the medical exam. He emailed the pdf of the application and also the medical examiner brought paper copies for us to sign. We went through the medical exam, but wanted to look through the application paperwork more (it was a big packet!) so decided to mail it instead of signing and handing it to the medical examiner. Now we have second thoughts about going through with the insurance. Are we obligated to purchase the insurance although we haven’t submitted the actual application?
We signed some papers with the examiner, one was for testing for HIV, another form that had two choices, one that said we gave the application to the examiner, second box that said that we didn’t hand it to the examiner and will send it in separately (checked the second box, signed, and gave the form to the examiner); not sure if we signed anything else (was very chaotic with our baby son fussing etc.).
Also, if we decide to cancel at this point without applying, would any info that we provided to the examiner go into the MIB?
Thank you!
