Should I gave her up?

I have a crush on coworker i like there is already 1 year, i very like her she notices it so its begin with i chat her first saying her is cute she is replay me and say can't word , later we be friend and do event together she take picture of mine with her only and never post it, she even say she is single, after 3 month doing this i not persue her like give her mixed signal

Later we join hiking and when i hiking insteead holding hand with her i choose another girl, i don't know she mad or not seem keep find these day

Tomorrow when i try to chat to her and say we have not take picture of US yesterday when hiking she left me on read and so on

Her behavior change and ignore me since i say we don't take picture of just 2 of US

But her when make eye contact with me she Will smile downward or smile i notices it, yeah its happen many Times sometimes she blushing

I keep persue her besides her is cold

4 month later i can't hold my feeling again i say i love her, she reject me say she does not have same feeling but when i stalk her, she followed love account on her tiktok (like red string theory or etc love relationship account) she never followed before US meet

Her friend say to me just gave up when i tell the truth with one of her friend

Sometimes her geng gonna ask me some information about her, do u like her or how u view about her , do you have a crush or do u don't scare her will find her soulmate they ask me this thing but i dont tell just smiles

And her geng know about my birthday, when i say birthday to her geng who i discuss about her, she say thanks i say our birthday day is same, she say yes and mine month her is know i shocked why she know i never tell everybody

The thing keep cold after confess and 1 month ago when her birthday i say birthday to her, she replay me thanks and i buy her Disney figure and later on her tiktok she followed acc the brand i gave her

Today i chat her she ignore me again

Should i talk to her directly and say i love her or gave up?

Should I gave her up?
