I met my boyfriend's dad and recognized him from a dating app

So I [F24] really don't know what to do with this information other than bury it deep deep down inside where no one can ever find it. About a year ago I went thru a pretty tough breakup with my ex (we were together for two years and were talking about getting married when he broke things off). As part of the relationship-grieving process, I got on several dating apps including some niche ones that didn't have too many people on them in my area. I had only been on this app for an hour before meeting a guy my age who I hit it off with. We exchanged snaps and I subsequently deleted the dating app. However while I was on there, I also messaged an older man (around mid 50s) that I thought was attractive and we were into the same stuff. Age gaps aren't my thing, but I was in a spot where I was willing to experiment a little.

In June of this past year I met my current boyfriend who is the love of my life. He's sweet, wholesome, hilarious, and we both love each other to no end. This man is truly my everything and I cannot emphasized that enough. Around Christmas he wanted me to meet his family (his parents are divorced and his dad has since remarried). Well fuck me I guess because I met his dad and recognized him as the same older guy I messaged on the dating app over a year ago. There is no way he knows who I am because I didn't have my picture or actual name on my profile. We had a very normal dinner and had a great time but it's been three months and I can't stop thinking about this realization.

There is absolutely no way I can tell my boyfriend this. I have no solid evidence to prove it was his dad other than my memory. But I'm so sure it was him. They looked the same, had the same name, and are from the same town (small rural). My dating account is deleted so I can't look back at our messages. I am also not interested in nuking my boyfriend's life, relationship with his dad, our relationship, and his dad's marriage over something I can only prove from memory. If I ever have hard evidence again, I'm not sure what I would do. But for now I'm taking this one to the grave. Thanks for listening.
