Awww Sorry Op! But I feel like if you ended it with "I'm a guy" would've been hilarious!

At least she thinks your gonna get laid

Now that I am thinking about this, it strikes me that the OP's mother might think she's firing up the OP to 'prove her wrong' and not get preggers and drop out. This is the type of crap my mother pulls. Despite having absolutely no education or background in psychology, my mother is convinced she is an expert in that field. She says she is 'using psychology' when she is actually lying and manipulating. If this were my mother, her rationale would be thus: "I probably didn't do a good enough job of teaching morals to my daughter since she was not a priority in my life, but I don't want her to embarrass us by getting knocked up. To cover up my poor effort I will tell her I am sure she is a *****, which will make her determined to keep her legs closed at all cost so she can prove me wrong, thus playing into my hands. Hence I will end up with a girl who will not embarrass us with a premarital pregnancy without ever having to go through the time and effort of talking to her about it." For my mother it's all about the end result and what the neighbors think. She is very proud that every neighbor with at least one daughter from our old street had a 'baby **** up' except our house and she takes full credit for that, telling one and all that it was her superior child raising skills which produced a daughter who didn't have a baby accident when in fact it was my own doing. She thinks this makes her better than everyone else and that the others are secretly jealous that my parents batted .1000 in the 'not having a shotgun wedding or bastard grandchild' sweepstakes.

She has faith in you.

Prove her wrong!!!!!

Ignore her, prove her wrong, no mother should ever say anything like that to her own kid no matter how old they are your mother should be supporting you.

Prove her wrong.

OP, it's been more than 4 years, have you proved your mother wrong?
