You can fight this.
Sounds like your bets are even. Don't worry about OW moving in yet. I know, I know it sounds almost impossible for you to do it right now, most of my stuff is still in the house (stbxh is staying there and I don't have free access to it) and the idea of who-knows-who going through my stuff grosses me out. And you know what... so what! It's stuff, I care not to care enough for it to own me. Talk to your L, come up with a plan what's best for you. Keep the focus on you, not him or ow.

P.S. Jeez, 80k for a house that is so affordable!
