Never break up just for her sake. Let her choose.
Long term relationships are about staying together through the good AND the bad. If she wants to support you through this rough time, then that's her decision. She wants to stay with you and there's nothing wrong with that. And if you stay together long term, there will surely come a time when she'll need your support, too.
