Before marriage he was like the best person ever....?

my husband was a perfect man a woman can ever have.and we were great with eachother.he took care of even minor details..alll these changes occurred a month after marriage.. being soooo bz that he went for work at 6 in morning and came back at 12 at night...did not recieve my cals during that time...if he ever recieved my call,being very rude to me..used abusive language occasionally..even wen i ws pregnant and alone at home..he never called a single time to ask about me..hez never affectionate..and tries to hide almost everything related to my inlaws...
