Yeah bring her a milkshake without a straw and then have her get sort of annoyed and make her pester and when she's about to walk over you pull the straw from your back pocket and laugh. Tease her... a lot. I'm short so if a guy was holding an item above my reach it would frustrate me. Don't answer her texts but then later on send a kissy emoji. Make fun of stuff she likes and then later on buy her an item of the thing she likes.
my friend... a complete asshole, so fucking honest that words he knows that will hurt you but true he will say it, no sugar coating and a brute and a playboy. damn but that big oaf can hold your hand while crossing the street and will carry heavy things for you without asking.
it's about the conviction behind it. being a combo works for most guys because they are a combo of nice and mean but if you are in fact a very mean person then be mean and that will work for you and likewise if you are honestly just a nice person who loves everyone be that and that will work.
girls can smell desperation so its trying to act in anyway to be attractive that will get her turned off.
"Bring her a milk shake without a straw?" lol Put a coat down over a puddle.. her coat Open the car down for her, but don't close it Wrestle with her.. but make her tap Her: "ow" You: "but did you die though? damn!"
Be nice as hell to her outside of the bedroom, be mean to who she doesn't like and show you're tough and dominant around those neither of you particularly care about. Be a oft hearted guy with any of her friends or family.
In the bedroom be mean as fuck but only the particular level she wants. If she wants you to be a nice guy in the bedroom dump her dominant ass ASAP (that last part is just my personal advice, technically it can work out if you're a self-hating mangirl)
