Take the same approach as home schooling. Community comes from engaging in other activities.

And then I'm a single father, so I'm just fucked!

It's something I've noticed in general.

I had an amazing boss who was single and lived alone, and really love her staff. We had unecessarily long staff meetings every week. When I started I was annoyed by them until someone pointed out that the time we spent with everyone getting distracted and going off-topic and padding out the meeting while we ate our lunch around the conference room table was, for her, the weekly family meal.

I still don't like unnecessary meetings, but it gave me a different perspective on why some people like them.

It's not about remote vs office work, but working remotely all the time reminds particularly painfully about not having a SO or many friends. When working from office, covertly texting a good acquaintance 2-3 times a day kinda replaces that. When at home, you could do much more of that, or probably bunch together to work, but you don't. Just sit there, smell your socks, sip tea, get distracted for nothing good, and feel how your life passes into abyss. When in office, you at least have the stress of many loud people around to distract you from that.
