I'm going to add to my post here, a little Oktoberfest goes a long way. Sorry for my tone.
I don't like that you were the OM. Plain and simple. That said, you got married, things went south, and now you're here. I'm sorry for that. Have you read many other threads? There's good advice all around, and sometimes looking at other situations help us in our own situations.
Why are you caught up with the verbal abuse thing? And what are the things that you did that have contributed to your wife wanting out of the marriage? How did you "pressure" your wife into marriage?
It sounds like you need to 180 on the pressure, 180 on the passive aggressive remarks towards her and your stepson., and 180 on being the rude and snobbish guy. What other areas would be a positive change for your life?
Earning her trust back will take time and action. Don't think you're going to talk your way out of this. The small, consistent changes is what Michele talks about making the biggest difference. Commit to some of these and make yourself a better man. Read the links. Read the book. Ask questions here.

It is not things that bother us, but the stories we tell ourselves about things.
