well i suspect that no matter how, she is not going to be happy about it, as she will be in denial denial denial.......but, try to do it at a time when you are both in a relaxed, good state of mind. start off, by telling her how much you love her,and care about her.how you hope that you have a future together.....then go from there. you may as well just come out with it. trust me on this, beating around the bush will just prolong yours and her misery.
