23andMe uncovered a horrible secret

I was 15 when it happened (now 21). I was young and in love and I slept with this guy once. We stayed friends and kept in touch afterwards. Recently, I've been finding relatives to me via the new map feature. In my immediate area, I find a lady who is my 4th cousin.... Who has his last name. I ask and he denies it. But then I decided to dig a little and found out that he actually is related to said person somehow (still missing pieces). So all in all, I slept with a cousin. It's a weird thing to process and he's still in denial, but here we are. 23andMe showed me that I need to dig into my family way more.

Edit: We have blood relatives connecting to her, so he's my cousin. It took about a month for my results

Edit: I don't believe I'm "overreacting" considering I only said it was weird. It's just an awkward thing and I know it'll pass 🤷🏾 Don't make a mountain out of a molehill
