Girls why do you think my crush did this?

[shallowsoda299]

so the flirting started 3 months ago the amount of flirting got bigger in march some days she flirts with me but some days she acts like i dont exist she did stare at me for a long time once but i got super shy and blushed alot i avoided eye contact me and her dont talk im too shy to talk to her so i decided to send her a request on instagram she saw my request and rejected why does she flirt with me but reject my request on insta??? i had an incident on with one of her good friends on instagram 7 months ago she knows what happned do you think that has to due with why she rejected my request???
Is she playing hard to get???
Is she playing mind games???
What i mean by flirting is staring at me,blushing and making eye contact with me
