A few things: Banking: get your money into an account in your name only. He can take every penny you have if it's a joint account, get him off your bank cards before he ruins your credit- do it anyway if he's unemployed and you stay together.
Medical: No makeup sex until an STD checkup. You don't want to live with a lifetime reminder of his bad decisions.
Counseling: get some, you both need it.
Stuff: sorry but when I was jobless, I picked up the slack around the house because in my relationship we are a TEAM.
Personal: we are exactly 5 years out from overcoming my husbands having an emotional affair- I busted him before it got too far and the other person told me everything because they were mad at being used and had the exact same thing happen to destroy their marriage. ( we talked for hours over days and she was super decent to me and I can never thank her enough) He was on a day trip with the "boys", by the time he got home I had him locked out of all banking, phone/text records pulled and highlighted, and his bags packed, took the car and house keys and showed him the door. It took a few months of counseling before he was back in the house, and trust takes longer. But our marriage is strong through constant communication!! That is the key, we are an open book to each other. Counseling was years for him- other unresolved childhood crap, he's great now and goes back for fine tuning as needed.
Oh, he knew what was coming when he got home because I did text him and say I hope he was enjoying his day with "Lola". (Ruin his trip) When he came in I was very calm- he said later that was what scared him the most, he expected yelling and screaming. Nope, cold, calm, collected. That's how you need to handle it.
You: get your financial house in order first, women are historically financially screwed in all divorces and since he's unemployed you may wind up paying him spousal support. Yeah, that would suck, sorry but 2 online classes doesn't mean he can't get a job - I teach so I know. Self worth is being productive. He needs to man up and support his family. That needs to be in your conversation if he's to return to your home.
