i have a girl friends,we fall in love for 4years,but now

It is good to be frank enough to her than wasting her previous time. I think it will be better if you get some courage and inform her how you feel about the relationship.

To give up is to give up this good for you.......come on...

It's sad that the 4 years will go to waste, if you end up breaking with your girlfriend. But some things are like that, they lose their angst. It will be best, if you will have an honest talk with your girlfriend. Point out your differences so that it could be cleared and remedied. You once loved her, so i guess a rekindling of the fire that was once with you, should be initiated by your girlfriend , but of course you too.

If you don't love her anymore, then set her free and find the right guy for her. Sometimes, it doesn't about how long had been your relationship lasts but what matters is your love for each other. If you care for her, tell the truth, even it means hurt to her, truth will set the both of you free.

Well, if you really can't settle your differences and you don't love her anymore, you have to tell her. She has the right to know. Pretending to love her would be more difficult. You just have to be honest with her. Not telling her immediately would just make things worse for the both of you. Telling either now or at a later time would still hurt her anyway so it's better not to prolong the agony.

You should not be coward with your feelings. If I were you I will tell her what I feel but before doing that, you should ask yourself first if thats what you truly feels or you're just thinking that way. The longer you keep it, the more pain you can give to her.
