I know the answer to this but disclaimer: I don't want to piss anyone off, so if this applies to anyone - Sorry.
It's common place for couples that are unhappy in their lives to always want to be out of the house. Even if they hate each other, they'd still rather be out in public places together than be inside the home where they don't have to filter how they feel or even worse have nothing to talk about.
Home is not a comfort to them. They don't see it as their safe space. At home they have no option other than to acknowledge that they can not tolerate the very basics of their lives that should have bonded them but hasn't. It's quite often seen in couples that have nothing in common other than their kids. No shared interests, no same future aspirations. The ones that are just existing along side each other, rather than together. Especially in couples that are completely different pages when it comes to the functionality of family life.
They will literally find anywhere to go and if not able, pile the house to the roof full of other people to take their minds of their day to day existence and find anything to avoid the conversation they should have, which is "What are we doing here?"
Anyway, a little bit of relationship/ family Psychology on a wet Sunday
