He's not really mines!

He was just sitting there watching me from a distance. I know him from a friend of the family and always wonder why he's watching me. He seems nice and all but he's one of my friends closest friend. I'd look up and I see him watching like he had never seen something so beautiful before but when I look up and he noticed that I've notice him looking at me he would turn to look away to pretend like he wasn't just staring me down. I think he's nice, I don't know for sure but he is completely off limits. He actually has a girlfriend and apparently she is not me. I was actually dating a friend of his. We were cool for a while, his friend and I but then I noticed after time, every time we were supposed to do something together he would send his friend and stay away. It got to the point where it seemed like I was dating him instead of his friend. In which he didn't mind because he got to spend time with me. He really enjoys spending time with me so much so that he became a bit over protective of me. The excuse he used was I can't be letting any one talk to my friend girlfriend. Yeah it was cute at 1st but then it got weird. We would go everywhere together even out of town. What's odd is he never told me why his friend always sent him instead of coming himself. So naturally I just assumed that he was there to babysit me and tell his friend everything that I did. So I played along with his little game not thinking that he would actually have feelings for me. And this is the beginning of our journey, a very unexpected one.
