UPDATE: My 3yo daughter told me that the OM went to my wife's work twice today and I couldn't keep quiet and I asked her why [OM] had to go to her work and she mad an excuse that he needed to take her something. She said that she is not going to stop talking to him.

I ended up in an R discussion and said she should leave the house and it looks like she is going to look for an apartment. Did I screw up? What can I do?

My wife is asking for a divorce and I don't completely understand why.
