Does this mean he's not a player or something ?!!?

Okay I made a fake account on Facebook with another girls picture . I made sure she was pretty obviously and I sent a message to this boy I'm recently liking. I dod it to see if he would flirt with another girl . I know he likes me cause he told me . So I messaged him yesterday as the fake girl saying "your type cute" , he replied with "thank you". Then I wrote "do you have a girlfriend"? , then he wrote no . So I asked him if likes someone now and he said yeah a girl in his school . Then I kept trying to catch him but he wouldn't let me he started saying to stop texting him and to leave him alone . Is he the type of boy to like one girl ??. I know it was wrong to make a fake account but I had to .
