Personally I feel there is nothing shallow about not dating someone cuz your not physically attracted to them. physical attraction is just as important as anything else. I do know though a lot of times you get to know someone and you click so well personality wise, that it literally alters the way you look at them...so someone you wouldn't normally find attractive suddenly becomes beautiful. On the other hand if there really is no physical attraction...there is no point in forcing it.
And since you know you cannot see yourself,
so well as by reflection, I, your glass,
will modestly discover to yourself,
that of yourself which you yet know not of.
