Bf only wants me in a short skirt
My bf wont go out with me unless i wear a short skirt no matter what the weather is or how cold. I dont want to lose him so i do it. My parents are not to keen on him,but everyone at school really likes him, if i leave the house wearing a pair of jeans i have to take a skirt with me and when we get around the corner he makes me put it on and hide the jeans in a bag to collect later before going home. Recently he has started lifting my skirt up at the back whenever someone is behind us, at first i thought it was a laugh,just a bit of fun but now he seems to hold it up more often and for longer and i'm feeling uncomfortable about it.
What should i do, he knows i dont want him to dump me
