"I just don't know how he'll react to anything I do/don't do."
You're right. You don't know. So don't even bother.
You can't control him. You can only control you.
Choose to GAL without him. Detach your emotions so his attacks will just bounce off of you. You are the strong one, not him. Live your life as if you were single. Let's face it. Right now you are.
M-43 W-40 2D - 9 and 5
Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
