Sarcastic spouse

Hye
Hi all,
​I need your advice. I've been married since earlier this year, but my relationship seems to go downhill ever since. 
​I noticed my parter couldn't admit his own mistake, when we were dating. i thought it was miscommunication. Now thay we're married, he's getting far worse.. He is always sarcastic when he's unhappy abt something and there's no way to communicate with him when that happens... Regardless you're admitting the mistake, talk positively, etc.. Nothing would work... It simply feels like talking to a wall...
​We had fights over small things very often. Most of the time, he wont give me a chance to explain.. he would cut me in and rambled and accusing me of things that never happened...
​It was okay for the first few times, i thought our relationship is relatively new, there are many things to be improved... But after we got married, he got even worse... He could scold me for crying... It was heart breaking to see my spouse treating me like dirt...
​One day we had a fight over something small, he didnt want to listen and instead he raised his voice.
​I got upset and he did too. He then ask me what I want, and told me: "just be honest so you dont have to waste your  time and my family's love".
​I was extremely hurt by that statement and lost my patience. I called it quit.. My bad.. But he never apologised to for starting the fire..
​He's been out of job since end of june  and just started looking for a job a few weeks ago. So far he has been asking money from me, as well as asking me to pay for all our bills and expenses. What made me sick is that he always wakes up late around 11am and busy reading soccer news or news most of the time. He will do what's necessary a day or a week later when he feel like it.. 
​We are on couples therapy, but he always behave very politely when talking to other people.. No sarcasm, no harsh words, just pure gentleman...
​It's hard to tell people of his true colour when he's always frieny and polite to everyone...  
​I am going crazy, I can't take this anymore. The word divorce keeps coming into my head, but am I seeing things properly or am I just exagerating?
​Somebody please tell me what to do.. I'm desperate!!!
