its just that when i do pay, she doesnt say thank you

she doesn't mind paying for herself purple

i know im not entitled to anything but i at least expect a thank you

i was very annoyed about it as the tickets cost quite a lot of money and i had to get time off work

she won't say thank you to me afterwards for that

e.g. going to cinema

if we are on a date, i will pay for what we are doing usually

yet she acts like couple with me

i asked her what we are, and she said that she isn't sure

she is also leaving me in quite a grey area
