How should i go about this??!?

she told you exactly how she feels. she has been thinking about this for a long time and even though she is under a lot of stress she was still very clear in communicating to you how she felt about you and hers relationship. you need to take her seriously and listen to her.. if she didn't mean what she said then she'll come back around then it will be up to you to decide what you want out of the relationship. until then you have to respect her opinion and what she says to be the truth.
