As you go through this very hard time in your life: WATCH yourself, PROTECT yourself, PROTECT your pocket...be cool headed. This WILL pass and in 10 years you will LONG way from this. So Protect your 10-years in-the-future- Self. Give him a chance if you want ( I wouldnt, cuz who wants such an selfish, disrespectful bastard around?), divorce him if you want, but always remember that you are legally responsible for him for the next 3 years.
Best of luck.
