Ya got you. I think the space she wants is emotional not physical. Some benefit to moving out in this respect but you'll loose out on opportunities to validate, connect, lead and all those "manly" virtues demanded of you and she may start an affair given she has it easy. Hard to change and GAL in the same house. Either way it's a slippery slope. When you're on one of these CYA.
Oh, I know it's emotional space she needs and wants.
I'll be seeing her every morning when I come over to get my girls ready for school. I'll also see her when she drops them off at my apartment on Mon/Tues. And I'll see her when I pick up the girls after church on Sundays. Plus she (or I depending on who has the girls) will be calling to say goodnight to our daughters each night. So lots of opportunities to connect.
I've also thought a lot about spending "family" time together for our movie night and Monopoly night, as well as Thanksgiving and Xmas. Those are pretty good opportunities to connect. I won't invite myself, and I won't be coming over every week for them, but I won't turn down any and all invites.
I can't stay in the house as a strategy to prevent her from having an affair. That never works.
