I know what you are going through. The same thing has happened to me. My parents were married for 34 years. My mom passed away 2 1/2 months ago. My dad would be out of the house most of the time. I guess being in the house reminds him alot of my mom. he would cry often. He does go out with other woman which bothered me and would also come back home late. I felt like my mom meant nothing to him. My dad was used to having my mom around and he loved her so much. I know deep down he loves my mom still. I still can't believe that my mom is gone. just wished it was a nightmare.
