Ended recent affair before submitting SF-86, will I be denied?

I’m single and had a sporadic affair (only met up a few times over a period of months). The guy is a foreign national with dual citizenship (also married) so while the SF-86 doesn’t ask about this, I might have to bring it up if asked about this contact during an interview. I have officially ended things and cut contact.

I will be filling out the SF-86 soon. I am open to discussing it and have already talked about this with some friends and family. I’m also single so I really don’t have anything over me to be blackmailed over.

I know this was stupid and it doesn’t excuse anything I did but during this time period, I also had major life stressors such as job loss, accident, and family situation that made me very vulnerable. I’d never had an affair before and I would never do it again.

I have accepted a new offer at a defense company and the clearance level is Secret, not TS. Should I continue to apply for other jobs if this hurts me and I get denied anyways?
