If he/she knows that islam treated men and women equally, and read the islamic POV, then he/she wont even think of leaving it.
Antiapartheid, islam is a feminist's religion as i have proven in my previous comment, so hopefully, you would return to the fold of islam, it is one of the least sexist religions in the world, it treats women how they should be treated, with respect, dignity, and love.
