I love a girl for 6 years but she keeps rejecting me, should I quit even I still like her alot?

After 6 years...I'm sorry, not much of a chance.
Get out of her life, if she notices you're gone and begs you to be with her, maybe.
Otherwise, go find someone else who has zero boyfriends, instead of two of them.

Uhm... 36-40 age range and you're in this dilemma? Ditch her, she's so not worth the time, you will know when the right person comes around who isn't somebody who just sleeps around - if she has two, she probably has had more!

well after 6 years and rejections i'd say time too move on. matter of fact you should have moved on years ago. apparently she's not interested, might even think your the stalker type if your persistent with your advances. just chill out and look around you, there are other women out there.

As the saying goes, 'If you love someone, set them free. If they come back they're yours. If not they never were.'

Start living your life! Move on ! Chances are slim she is into you more than a friend.The sooner you accept this the better for you in the long run xx

NO that ***** is not worth your time. same type of **** happen to me recently go read my last question you will understand. Never be 2nd choice! Even if you do get her most likely you wont be happy cuz she will not love you like you love her so One sided love is never good.
To some people time is worth nothing while to others even one minute is allot if she dont care about u for past 6 years and decided to fxxk other men then why you care?
Love is only good when it keeps you happy when it turns into sadness then find a solution try it if dont work then move on. Good Luck and shes not worth your time and effort give your self about 2 months to clear your head and find your self another girl to run after :-) .

It's like owning a beautiful car that just wont go. Sooner or later you have to get rid of it,or be stuck with a "Lemon"

Dang boy, you need to move on yesterday.
