Sometimes too much we give everything to someone and they never appreciates it its like that kind of you wanted to giving up, but believe me just keep on holding on and dont give up I know she can appreciate it in the right time. but when it takes a long well its time to think also your own happiness so many girls out there you can find more deserving than her
Ah good question. That is the hardest part. I mean you could still show her that you still love her for weeks or months till she realizes that you mean it. Honestly its the best idea to find a girl who really loves you. Its your choice. Follow your heart. I have been having this situation for long time. The key is patients. It might be a pain as a bee sting but you will get through it. Good luck
Smile, wave, say hi. don't stalk or be rude/weird. if that doesn't work pay no attention to her for a while and see if she notices that. anyway, if she's really not that into you, then just leave her alone.
