Should I (25f) tell my girlfriend (28f) that I only met her on a dating app because I already knew I could find her there?

Before we started dating, my girlfriend was a friend-of-a-friend who I didn't really know in real life. I followed her on social media and really liked her personality based on her posts. She occasionally posted about how she never found anyone good on dating apps. I've always thought it's really transparent and kinda aggressive to "slide into someone's DMs," so I was more comfortable with the idea of meeting on a dating app. She lives in my city, so all I had to do was download several popular apps and swipe through until I found her. Lo and behold we matched and I played it off as a coincidence that we had mutual friends.

Fast forward to now and I feel a little weird that she doesn't know how our relationship really started. Was it wrong to do this in the first place? Should I tell her? I don't know how she would react.

I actually had a guy confess to doing the exact same thing to me a few years ago and I was a little unsure how I felt about it at the time. I had just gotten out of a relationship but I decided to get on dating apps right away. I matched with a guy I didn't know very well from my college program and we started dating. A little while into the relationship and he confessed that he only downloaded the dating app because he heard I was single and swiped left on every person until he found me.

That wasn't why the relationship ultimately didn't work out. In my opinion he's a normal well-adjusted guy, he just wasn't the right person for me. I thought it was odd but it didn't make me feel uncomfortable because I already knew him well enough when he told me that I trusted he didn't have any bad intentions doing it. I also didn't think it would be an issue even if he never told me. I figured it doesn't matter how he matched with me because I swiped right on him of my own volition.

Since I was okay with it when it happened to me I didn't really think twice before I did it to someone else, but I'm worried that if my girlfriend knew the truth she might feel differently.
