i like a girl,but she already had a boyfriend,should i stop

Do u wanna me 2 answer this question?If i was i will tell that girl wat im thinking and my emotion.Try u best to get her.However,all u guys should let the girl decide.
If i ask u,lets say if u wanna stop loving her.CAN U really just stop!human emotions are really complex!u cant stop that just by saying.
Also,u shouldnt ask for some1 else to help u 2 decide this type of thing.That's u own business!try 2 solve it by urself!(sometimes use u fist)
