You really need to let go of trying to guess what she might be thinking, feeling, wanting. You will not find the silver bullet you are hoping for. The only way throug this is to focus on yourself and your wellbeing, emotional, physical, mental, financial and legal. Excercise, sleep, GAL. This is paramount.

Do not spend your time watching over your shoulder if she is pissy, hissy of any other type of-issy. Her mind must be racing in a million different directions and you need to let that go. Every time she is in a bad mood, I bet you are wondering what did you do wrong, or how to "fix" things for her. You can't, so, don't even try. She will only resent you for it.

Time to become a man. Becoming Scott 2.0 is for you, not for her.

Stay strong.
