Q&A What Can I do Since my Husband is Still in His Affair?

My husband is still active in his affair. He is struggling. We are still in the same home, separate rooms. We have no kids. He hasn't filed for divorce nor when I ask him do I need to do this, he says no. I feel stuck. Note that his affair partner's divorce was finalized last month. I have backed off questioning him about anything as my recovery is difficult when the affair is still going on. It makes me wonder if she is now pressuring him to get a divorce. Anything I can do? Thanks...
