All People You Meet Online Are Bad

I am dating this wonderful guy. We've been dating for almost 4 months He makes me feel like the only girl in the world. I don't particularly care for what others have to say about my relationship or how I met him. My stepmom dare question him (hasn't even met the guy yet) and say bad things about him. She says all men yo meet online are no good pigs.. That offended me. I have no clue why. But it did. She thinks he's playing me And all he wants is sex. Which isn't true. I just can't shake what she said out of myhead...
