dude though many people had said the same thing, i'll still say
it again. Love is really not about money...though urban legend has
it that girls love guys with big wallet..its really more than that.
I think you are the type that treats her everytime the both of you
goes out..thats not right man, i'm also schooling, thats why i'll
go dutch with her sometimes. If you think its embarassing to ask
her to pay herself, do like what i did, "eh you owe me [amount of
money] for [that particular food] ah". Say in a playful mood so she
wont sense that embarrassment, but as time passes, she will pay for
her share of things too.
And btw..what the hell you change your plan now for? you are just
burning abohter 100-200 bucks for pete sake. If you really want to
spend more on valentine with her, change your plan next time when
you not that strapped of cash.
