My wife kicked me out of the house?

Hello my name is Simon Lam and my wife, Sarah, and I have been married for about a two years or so and we own a house together. I am the one that pays for house and deals with the mortgage payments and etc. My wife is a stay at home mother for our 1 year old baby. Recently, we had a huge argument and she told me get out of the house. I left and got really drunk and ended up going to the bar and ended up sleeping with my ex-girlfriend Eleanor. I felt really guilty for this and didn't want to keep it a secret so I told my wife what happened and told her I was sorry and it was a huge mistake. Immediately she blew up on me, started hitting me with whatever she could find and told me she wanted a divorce and that shes taking the house and that I can go "**** myself". Excuse my language but hold on here, I pay EVERYTHING for the house and she doesn't provide ANYTHING to the house so I feel like I'm entitled to everything. She is adamant on this divorce and insists on taking the house, however I know some pretty powerful people that can get me a very good lawyer. I think I can get end winning the case if this goes to trial and end up suing him for some other stuff. What do you guys suggest I do?
