I Am a Hopless Romantic

I like a guy but he never acknowledges me and not sure what to do about him. Recently, I saw him with his shirt off while he was doing work outside of his house. I honestly felt like I was in ''Call Me Maybe'' music video by Carly Rae Jepson xD. I couldn't help to stare as much as I felt like a creep standing there all while listening to random music on Spotify. I even waved hi to him from afar, he pretty much gave a quick glance at me and kept on going with his business. My heart sunk a little all while I was imagining what would it be if I dated him. I can't get rid of the shirtless image since his my type physically. I don't know, he may have a girlfriend since that always seems that case of the type of guys I like...:/
