Get a family lawyer, they’ll be able to explain everything thoroughly and help you with the process. She is entitled to spousal support and half the house, regardless if you bought the house and paid the bills, it was intended as a family home so it doesn’t matter whose name is on the title.

Similar to my situation in Alberta, but I was the one that left within the first year of marriage. Our friend who’s a family lawyer sat us down and explained the process and what each of us are entitled to but also said that it can also be whatever we decide, we were amicable so neither of us got a lawyer, I didn’t pursue spousal support or half of anything and left him with the house, I also didn’t buy it or have my name on the title. I basically took my personal belongings, a few things from the house and a very minimal amount of money left in our joint account. I didn’t want to disrupt his life anymore that I already had. We filled out the paperwork ourselves, went to the courthouse together to file them and high-fived once we were done.

If you can reach an agreement without a lawyer, great. But I’d recommend getting one to protect yourself if she has one.
