I'm not sure I have much of value to contribute, but it's ridiculous that he's been having an affair, saying he wants to separate, and is surprised and upset that you moved his stuff out of the MBR.

"I never said our relationship was over, that I wanted to end things. People separate, work things out, and get back together."

Yes, people sometimes get back together when they both commit to each other again and do the hard work of fixing themselves and their relationship. That does not mean you should carry on like everything's normal while he has an affair and muses out loud about leaving the house. Would he skip half the days at work, miss deadlines, and tell his boss, "No need for you to take action, sometimes people are bad employees for a spell then get it together again."
