YTA. Its not even a question. Im just gonna start with the the fact that you asked her half way through dinner if she wanted to have sex. All the ghosting shit is irrelevent after that. You dont ask a girl for sex half way through dinner on the first fucking date, are you serious. This is how im picturing the scenario in my head. Your both 16 or 17, you asked if she wanted to go on a date to McDonalds. You bought her a medium fry and a small McFlurry and thought that should be enough for sex so then you pop the question. She says no, then you act like the entitled baby you are.You drop her off in your moms vehicle and then think your cool when you ghost her. 100% your a dick.
