You have certain expectations on how a guy should or should not
behave during dates.
He, on the other hand, has different standards on acceptable
behavior too. And both your opinions, while valid, are not entirely
matching - no big surprise there , because we're all different . So
I don't think you can blame him or yourself for that. (Unless he
was downright rude or had insulted you, then that's a different
story. )
If you don't like what he did , you could either tell him and hope
he will respect your sensitivities and won't do it again. Or if he
repeatedly makes this faux pas and you can't take it, then don't
continue dating him. Not all men will make big changes for a girl
they've only dated twice.
