Okay well ive been getting pretty serious with this girl ive met a while ago, and today, at her highschool, her brother saw us kiss, so the fucking douche goes and tells her that im cheating on her, now her mom is like some 70 year old who controlls over evryone(or at least tries), so about 2 hours ago i got a call, and she dumped me,
Because her mother was threatening to send her away, so now totse, i am asking you, what can i do to get this girls mom to get to know me?:(
Sorry if this didnt make any sense im sorry, i just kindof had to vent

Punch her in the tits.

Talk to her brother, and unless he's a psycho, you should be able to convince him you're at least an OK guy. If her mom will listen, you should try and meet her and make a good, respectable impression (i.e. whatever aspects about you are philanthropic or responsible).

Faling that, use stealth. If your girlfriend isn't willing to lie to her parents to escape their ridiculous restrictions, she doesn't really love you.
