Last thing he just texted me when we were discussing a home repair was, “I feel like you should make the house decisions”. I know he wants me to read this as, since he’s moving out the house is mine to make the decisions. Not sure what to respond.
Not sure of the nature of the decisions you're talking about and what the money implications are, but unless you're burdening him with a lot of costs then I would go ahead and make the decisions yourself and proceed. I understand your concern that he thought you were too controlling before, but he's checked out now and you can't fix that in the relationship for now. Plus you've got to consider how much of that is really just rewriting of history. Were you really controlling or were you just stepping up because he wasn't? Right now he's looking for any ammo he can to use against you, even if it's completely fabricated or exaggerated.
