I am sorry to hear it. It can’t be easy.

Whose place is it or are you renting? I’d consult with a lawyer immediately. In my understanding your location recognizes common law so you might go through division of assets if you have any and you definitely need to establish child support payments very quickly.

I’d not be writing any kind of letters but I’d be consulting with a lawyer today. Some might be doing it virtually but you can get a lawyer and you gotta do it quick so you know where you stand
