Strictly speaking, the issue isn't that she'll be upset, it's how you'll feel about her being upset. Doesn't seem like it's about her, it's about you. Maybe you're wondering whether you're really a good person if you keep hurting her like this. Maybe you'd just like some reassurance: I absolve you of the pain you will cause. It sucks but it's a part of life, her life and your life. You can't coddle people forever, especially not at the expense of your own life. You have a responsibility to yourself and you have a responsibility to her to end it rather than prolong it because you don't have the courage to see her upset at you. That's her problem and you can be there to help her get over it (if she is motivated enough to), but that's where your responsibility ends. You don't have to feel guilty about this. You're still a good person. Good people can cause pain, however they do it in the name of a better higher cause rather than pain for th sake of pain.

Finally, you can do it. You can do it and you can handle her pain afterward and you can handle your own guilt afterward and you'll be ok and in the long run she'll be OK. Good luck!
