You may feel guilty, joyful, confused, scared, sad, or even angry. In a situation like this where feelings may be complicated, connecting with and attempting to understand what your partner is also feeling may be helpful.
However you may feel, know that focusing on fault, placing blame, or questioning why it happened will not be beneficial when faced with moving forward and making decisions.
Instead, try to put your energy into the present and the future. Let your partner know that you are there for her, you are in this together, and will do what you can to help.
