I’m confused...help?

Me and this guy have been talking for a little over a month now and we flirt a lot. We send “xo”, call each other cute/hot and other things. I posted on my Snapchat story a quote that said “I want to bury my head in someone chest and fall asleep and 4 hours later I wake up and I’m still in their arms” with the “👀💕” emojis and he sent the two exact same emojis back so like yeah. About 5-10 minutes ago, I posted on my story “it’s nearly my birthday” (a selfie of me) because it’s tomorrow and he swiped up saying “oh my LORRRDDDD 😻🤩” I just joked around and said “ewww noooo” then he sent something like “you’re so pretty xo” lmao my dumbass said “holy shiiitttt I like youuuu” HAHAHA GOOD JOB but now I’m confused because he said “Aww. You too xx” like what is that? What does that mean? Helpppp
