This guy has a girlfriend, why is he still talking to/teasing me?

Anonymous
this guy iv known for quite a while who I used to like and still kinda do, is constantly teasing me or trying to get on my nerves or something! he gets involved in everything, like if I leave my guy friends messages on their Facebook, and they write back, he'll comment and try to make these stupid jokes to annoy me or something. he keeps doing it! and he annoyed me so much one time, that I stopped speaking him all together.then he text me out of the blue asking why I hate him in a jokey way and we became friendly again and he text me a few more times too, sometimes he flirty. but the catch is..he has a girlfriend, which is why its so frustrating.cos if he has a girlfriend why does he feel the need to talk to or tease me?does he just hate me or something? he used to e nice, he turned kinda mean when he found out his mate liked me and from then he's won't stop teasing. guys views would be great.
