My suspicions were that he was drinking, but when I'd confront him he said no and gave me either reasonable answers or made me feel that I was judging him. I started to feel like I was going a little crazy, feeling like I was overly paranoid.
I remember when I discovered that my husband was an alcoholic. Although it was very painful it also helped me see things clearly. Knowing what the problem was....it helped me make sense of things rather than feeling crazy.
