American income life insurance- Cancellation Question

Hi So i’m kind of dumb, my boyfriend signed up for some life insurance at 25 for $80 a month. The guy said he can’t change this amount for six months. And that the application process for this takes anywhere from 4-6 weeks and he needs to do a physical and see if he gets accepted into the insurance. We immediately regretted as soon as we signed all the forms and contacted the guy immediately to stop the process as we had no idea what we were doing. He was contacted through his union by mail and now we are super nervous that we are stuck paying for this for the next six months. And the guy hasn’t replied to us yet. I’m not sure what to do because we haven’t even been assigned a policy number or anything yet nor done the physical or anything, just signed some forms online detailing the stuff about the policy and everything. But now we don’t want to do it and we feel so stupid (we are i know i’m sorry) Can we cancel this in any way? Like i said we already send the guy a message and are going to call tomorrow to find out more info but are freaking out at this point since we have no solid answers and couldn’t find anything online regarding this. pls help 🙁
