in, how do I get my husband to move in?

@Musicalvibe Hi! Is your husband another players Sim (blue plumb bob over his head) or is he one of the Sim Townies? 

Welcome to the AHQ Forums too! ☺

He’s a townie from what I see. I don’t see anything over his head

@Musicalvibe If that's the case and they are married, he should automatically move in. The only time I've seen a problem is if the NPC is an elder. He doesn't have dark gray hair and a hunched over back does he?

@Musicalvibe I've never done it but there should be an interaction where you ask him to move in. When you tap on him scroll through the options and see if you see an option to "Move In". ☺

He'll need to be at level 8 minimum in a relationship with your Sim to move in, though. And townies sometimes age up without warning, so don't delay!
