try to express your love with acts not with words....women usually asking the things you don't do.
so invite her to a restuarant , a walk in corniche , a movie night, ...you know ...these activities that make you both share a beautiful memories.
and expect anything, but i don't think that she doesn't love you.
it is you only who demanding too much.

i had an experience before with a girl i loved..she asked me to play a game, she will say a word and i have to repaly immediately what is in my mind when i hear this word...i hesitateed..and it ended up with a big fight.
after few months , we played the game again, but i had to ask ...she hesitated a lot , my reply was a smile, so it depends on the person himself.

don't be demanding too much, don't let your thought kill you, and don't make judgments on the word "i think"
