Wow, I really don't know what to say to that mate. All I can say is that I've loved before and it was the best feeling in the world but I still can't understand how something so great and so amazing can turn your whole world upside down and bring so much misery and pain at the same time. I've been through it and I wouldn't wish it on anyone. Being with someone for that period of time though I can't comprehend why your partner would want to call it a day now. It must have been on her mind for some time. Leave it for a few days to get your thoughts together then meet with her and let your feelings out and find out the reason why she feels the way she does. You cannot force her into loving you unfortunately mate if she doesn't any more or not as much as she first did. Hang in there.
