how do you know that you're inlove?

Oh boy y'all so i met this guy about 3 weeks ago and I've never felt this way about anyone ever. We talk everyday all day, have a ton in common, support tf out of eachother, hype eachother up like everything is so great. I've only hung out with him twice and both times he slept over and we had sex. I don't think I've ever been fucked like this in my life ladies 😂😂

he isn't super affectionate towards me like we cuddle and stuff but that's it but we talk for hours and hours when we hangout and I feel like I can just listen to him talk forever. I've never felt this way with anyone what did it feel like to you when you fell inlove? I feel awkward and shy around him but I think that's cause I'm so into him I don't know how to act lol but at the same time I'm totally fine with how things are right now like I don't feel rushed into wanting a relationship or anything.
