Did I accidentally offend him with my crappy flirting?

So there's this guy I have a huge crush on. I know it sounds like middle school, but he's really out of my leauge, but also I really like him. We've known each other since like, birth, and he's just gotten cuter as we get older. We'll, I found an old childhood pic and sent it to him. He basically said it was awesome, and I had the *brilliant* idea to be like "Right? Back in our prime lol" but like I meant that sarcastically. He texted back something along the lines of "LOL that's right," so I'm hoping he took it how I meant it, but guys, would you be offended by that?
