Indeed, if you could try to type in better English and using paragraphs, that would help a lot.
I don't know, but maybe this teacher feels like you are performing badly at maths, and wants you to do better. He's been talking to your parents at the parent teacher night, he's been 'watching' your music performance, he's been asking you whether you understand or not, he's been asking whether you have a boyfriend ('love' does affect your studies)... but you say that he hardly helps you... that's weird.
May I ask what are your current standing in the class in Maths? Are you on the bottom of the list? If so, that may be why he is 'focused' more on you. What about if you got better grades? We can help you with things that you don't understand if you want, here.
Yes, I also suggest that you inform your parents about it, if it was not already done.
Concerning that part:
Then came parent teacher night and he was lyk to my gguardian that she is doing real bad in maths and has really bad attitude.
Are you sure it is what he said, or do you think that is what he said, by how your parents reacted towards you? Because if he told your parents that you were performing badly, they will tell you, maybe severely, that you should work harder. And then, you might have guessed that he also told them that 'you had a bad attitude'.
