Hey tlankong,
I personally just ended a relationship with my gf of 3 years. It was painful experience for sure. I know you have feelings for her & envision both of you together in the future. But you need to realize that through all your conversations with her, that she does not view you in the same way.
A relationship is something that can only exist & flourish when 2 individuals commit to it & work towards the same goal. She is NOT the one for you. She is NOT your destiny. You WILL meet a girl one day that makes you feel like you are complete, yearning for your ex is just your mind not moving on.
I know how you feel & my thoughts goes out for you. I wish you the best of success in moving out of this circle of regret & achieving your true happiness in life.
Sometime is good to let go now, & you will give yourself a pat on shoulder IF this type of issue happen when you are married & wid child.
Yes, 6 years is hard to let go. My ex of 5 years, i also went siao overnight...haha
If really cannot get her back, go for other females, i know there will be no 1 that can replace her but change a new may have a better future, maybe the new person is the right one for you.
As per your topic> I will give some time,show her you dun have her will not die. Then go to places she go, chat up & slowely win her heart back, showing her the new you. It will take time tho..Most of the time, if you hv new social circle, you will get another new partner.
Good Luck.
