Seems like you are doing OK. Just remember to take care of yourself (and your child) first. All of your actions should be focused on the care of your daughter and your mental and physical well-being. I lost 12 pounds in the drama prior to me discovery the A, that was about 10% of my total body weight. As one of my friends said, "die FOR your wife, not BECAUSE of your wife." Do not deny your feelings. You wouldn't be on this website if you were hoping to get a divorce. You wouldn't be analyzing her behavior if you wanted out. You wouldn't be quite as amped up for the next dance if you wanted out. The reason I tell you that is so that you remember to go through the entire grieving process. If you don't, you'll get stuck and most be able to accept the situation and make the best decision on how to handle it. People's decision-making processes are not as logical when they are desperate or scared. That's how she's in that situation, and how she can't get out of it right now even though I suspect that she wants to. Keep going, you will be fine!!
