Strongr - I know you're going through a rough time. Do something for yourself. Take a walk. Rent a movie. Something - anything - just do something completely for yourself.
I know how much it hurts. My husband is being "guided" by another woman! I'm just focusing on myself. What I can change. What I want to be. How I can get there. If I focused on him, I would lose my mind.
I know this is harder than anything...I'm right there with you. But it really does help if you start to look at this whole situation as a time to work on yourself. Be nice to yourself.
