The first inclination of an impending earthquake

I am not sure how I got in this situation.  I felt up until about 3 months ago I had the white picket fence, cute family pet, children that occasionally misbehaved but loved me and a husband that loved me as well despite our occasional disagreements.

I've read that before a tsunami things are eerily quiet.  The wind may blow but there is a noticeable calm before destruction.  I found that true in the destruction of my marriage.  The first crack in our marriage appeared when my husband began going out late at night with his "sister".  My husband groomed himself as if he was getting ready to grace the cover of GQ.  I thought to myself what a waste of a decent looking guy.  Why spend time with his sister instead of his wife and kids?  No romantic dinner, no movie with friends and coffee, it was he and his sister.  Call it the parent in me but what good thing could he be doing leaving home at midnight-nothing goes on at that time but no good.  I was bombarded with criticism on the way I dressed, the amount that I weighed, and the frequency of my workouts, what I ate, etc.  I felt like I was sinking deeper and deeper in a hole I didn't want to be at.

Despite these cracks, there was a strange calmness.   I can't really describe it, it was more a feeling than a reality.  My husband and I began leading separate lives.  I rarely spoke to him during the day, never emailed him, and rarely even spoke to him at all.  We lived in the same life but were other than our home and kids leading mutually exclusive lives.

As a mom my first priority was protecting my kids and of course my marriage.  I foolishly let my husband sleep in from his late night/early morning binges.  I made certain that the kids didn't disturb my husband.  I kept things from them when my son asked me where dad went out so late, and of course I hid my increasing depression from my kids. 

My work and social life began suffering.  I didn't want to go out with friends, I preferred to stay home but at the same time didn't want to stay home with him.  I began fearing divorce and had no idea why I felt this way or if it were going to happen.  It was if I was in a dark corner with nowhere to go.
