You are afraid that she will bolt. It's understandable. However, you can't allow her to treat you like the bug exterminator either. Pick a time that appears good to have a chat and do it. Nothing ventured, nothing gained. At least she'll become aware of how you feel about things. Don't be surprised if she gets angry or acts all defensive...it's the normal behavior for mlcers. Stay cool, calm and collected. Do not raise your voice...keep your voice even and calm.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
