This guy give me butterflies and it’s been a min

So yesterday at work there was this guy who came in I can tell he was staring at me I admit I was staring at him too he was cute and hot, 5 min later he came up to me and he wanted to get to know me like what I liked what I was into I admit It was awkward I was even blushing lol because I never had no one come up to me and try to talk to me ask me what I liked we had some stuff in common I was surprised we liked the same stuff but one thing I admit I can’t stop thinking about him since yesterday I am in a relationship is just my bf idk he hasn’t made me feel special or give me butterflies as before at times I feel like i’m the only one trying.
